[Plugin: Jazzy Forms] hook multiple forms together?

That’s not possible at the time of writing.

Some thoughts on this: basically I can image two different scenarios
1) Two forms on the same page. One form would want to access data from the other one. Some kind of addressing notation similar to the one used in spreadsheet programs might be useful: another_sheet!some_id. Currently forms don’t have IDs.

2) One form submission is leading to another form. If forms were able to get default values from an incoming HTTP request and submit their data through another outgoing HTTP request, you could in fact hook multiple forms together, propagating data from one to the other. The challenge for me here is to present that in the GUI and to keep it simple.

Anyway, none of these is implemented yet.
