How to replace audio after cuts have been edited?

I have a 20 min video that has been edited with many cuts down to 1 min.

I then have a new enhanced audio that comes in later, however it's the full 20 min and did not make it into the edit during the editing process.

This is so that re-edits that can be made later to include new segments with enhanced audio ready to go.

This workflow repeats due to various reasons - in this event, how can one replace the audio?

I have tried:

- Alt Dragging the 20min enhanced audio onto the edited audio cuts in the 1min, however they all start from 0, instead of aligning timecodes

- Right click -- Synchronize, which is greyed out

- Replace with clip - from bin - same result as Alt dragging.

Other than previous workflow modifications, is there a solution for this circumstance? 
I'm not looking on ways to prevent this, I know them, I'm looking for ways around it

If new file is exactly the same length:

Try replace footage in the Project panel (right click on clip).

Hi Ann - I can't use Replace Footage, because while it might replace the audio as needed, it then removes the video.
Is there a way to replace only the audio layer of that footage?

Create a new sequence with the original video and audio on the timeline.

Replace the original audio with the enhanced audio.

Export to a virtually lossless intermediate file like ProRes.

Replace the original file in the Project Panel with the intermediate file.

Thanks @Peru Bob looks like this is the only workaround but it is quite a cumbersome one at that.
It would be great to have the option to alt-drag replace while maintining timecode/part that was cut, or at least a better solution

Here's how you can replace audio after cuts have been edited in your sequence:

Step 1: Create a Duplicate Sequence with Duplicate Media

1. Save your project file.
2. Go to File > Import and select the project file you're working in.
3. In the Import Project window, choose Import Selected Sequences and check the box for Allow Importing Duplicate Media.
4. This will import a copy of your sequence along with duplicate media.

Step 2: Replace Media

1. In the Project panel, select the 20-minute video file and go to Clip > Replace Footage.
2. Select the mixed audio file to replace the footage.
3. You’ll see a prompt warning that the file doesn't contain video and that video references will be removed from the sequence. Click OK.
4. Your new timeline will now have the same cuts, but it will reference the new audio file.

Step 3: Add the New Media to Your Original Sequence

1. In the updated timeline, select all the edits and copy them.
2. Paste the edits into a new track in your original timeline.
3. Mute the original unmixed audio track to complete the process.
