P: Can we please export with option to name subfolder the filename

That's my system. I name the files by date and event name:  2023-08-18-DowntownSanDiego, letting LrC append the number starting with 0001. 

I also use that same name for the folder. To save retyping, I copy the file name field and past it into the folder name making sure it is a subfolder of my master photos folder.

The OP's idea would be helpful if there was a check box to: "Use Base File Name As Subfolder Name".

The reason why is because it then makes it very symple for me to upload my files and make galleries with the correct names without me trying to individually name each gallery. If I say have a file, with 123456.jpg in folder 123456 it streamlines my process. 

Like the Legend Mr Golding, I too am unclear of what you want or why. 
I am hearing you saying you want file xxxx.jpg in subfolder xxxx  and file xxxy.jpg in subfolder xxxy???  Why would you want that??? 

I have a large amount of files I need to export and put into folders of the same name. It gives us the option to name the sub folder however it does not give us an option to name it the file name. 

I am clearly confused, and I suspect I am about to make a bad assumption, so instead of trying to answer, I will ask:

Can you give an example.
