I wonder if it's possible to upload a file to this list.

I work with mass files, and could export an excel or xml file with all the parameters instead of having to manually register them ...
- I downloaded the Developer mode (I am a student of this area) and found the file
"\ antrenamer2_sources \ Renamer \ dev \ default.xml" I suppose this is the base XML to insert a distinguished list, the problem is, WHERE IS THIS FILE LOCATED IN THE USER VERSION ??
Is it possible to implement a "load / open" button, or is there any way to do this?
Thank you!
