Wish Backup of additional project files

The "Export as zip" is a fast and convenient way to backup a project.
However it does not account for extra files like a .bat file used to compile the project with B4ABuilder.exe that is located in the project directory itself?
Is there a way to include files like that in a project export?

Not ideal but you can put the batch file in the Files folder.

I was thinking about that, but it would mean it will be copied to the device at runtime also.
This is viable only if the file doesn’t contain any sensitive information, like a password or something alike.
