Dear @funeral-studio
I understand what you mean, currently there is no built in option for this however:
A projects Gridder "JSON" is available:

Via:
Screen Options > Gridder JSON >
With this information you may find it easier to copy and paste Projects into one.
Hope this helps and best wishes @funeral-studio 🌼
Sincerely
Richard
