Best practice for “packaging” manually synced video + lav audio so it can be reused across timelines?

Looking for a best-practice workflow question here.

I have a sit-down interview clip (camera video + scratch audio), and I recorded clean lav audio separately to internal storage (DJI Mic 2). I manually synced the lav WAV files to the camera clip in the timeline.

So in my sequence, I now have:

• 1 video clip (camera)

• Multiple synced lav audio tracks underneath (muted scratch audio)

• Everything lined up and working properly

Now I’m trying to organize my project better.

What I want:

I’d like to create some kind of “container” in the Project panel where this synced setup lives as one reusable item — so I can:

• Put it into bins (e.g., “Sit-Down Interviews,” “Walk-and-Talks,” etc.)

• Drag it into new timelines

• Have all the synced audio tracks follow automatically

• Avoid exporting or rendering new media if possible

Basically: I want to treat this synced setup like a single reusable master clip that I can drop into other sequences.

What’s the cleanest, most professional way to do this?

Some options I’m considering but not sure about:

• Merge Clips?

• Multicam?

• Nesting and dragging the nested sequence into bins?

• Creating sub-sequences as “source” sequences?

• Something else entirely?

I’d love to know what experienced editors consider best practice for this type of workflow, especially when organizing larger documentary projects with lots of interview setups.

Thanks in advance 🙏
