Hello.....my suggestion....."Save a jam as a template" and "Load a template as a jam".

Many Itch members like to make series of jams( I meant: Jam #1, Jam #2, Jam #3, etc. ) 

Forexample: I published Jam for All BASIC Dialects (#1) to Jam for All BASIC Dialects (#6)   
( https://rcbasicfans.itch.io/ )

If the two features are added to Itch jam system, jam organizers(like me) will be able to make series of jams conveniently.( only do slight modifications on templates. Sure!)

I hope that the management team of Itch will consider this suggestion very closely. Thank you very much! Thanks again!!!!!!
