You can try this AutoHotKey, if you don't have AutoHotKey install it https://www.autohotkey.com/
set it to Always On Top,
it will save every 2mins (120000)
Code:
#Persistent
SetTimer, BiabSaveAs, 120000
return


this is just a basic test model, a timer selector can be added to adjust
time between saves, but for now just edit the script in Notepad to change the mins in milliseconds.
Close the GUI to stop saving.
If BB is playing it will pause and save then continue playing.
It can be added to the Chord Picker Tool.
**Try it out on a test song that is a copy of your original.
You should get:

my song.SGU
my song[001].SGU
my song[002].SGU
my song[003].SGU
etc...

It can be modified to work on any other app.

Remove the .mp4 and unzip and run.
