Scan naming doesn't rename the file

[ElucGeek]

When naming or renaming a scan in the app, it's effectively listed with the chosen name but the file itself still has an auto-name: SCANNED_dd-mm-yyyy_hh-mm-ss.pdf
Would it be possible to change it by the selected name or to have the name after the date/time or date+category+name or to be able to choose how the file name is constructed form settings? Even better if the files could as well be sorted in sub-folder by category name it would be perfect for syncing the PDF scanner with a private server or cloud.
When I want to share the file it's a bit of a bummer to have this generic name and not the one I carefully entered for my document.

Exactly my need. Can you give some guidance where to make the change myself and submit pull request? EDIT: found it

I have made the changes in my fork, basically also removed the timestamp. Can anyone help me to generate the apk? I tried in android studio but I'm getting compilation errors I can't solve, I'm not a java developer. https://github.com/Ljupch0/CleanSCAN
