[Feature Request] Allow copying / moving fields between parties

[pirate]

Currently there is an option to copy a field to all pages, but no option to copy a field to all parties.

It would be very useful to be able to move or copy fields between parties.

It would allow for:

• If fields were created for the wrong party by accident they could be bulk moved to the correct party
• If multiple parties have to fill out a big sequence of similar fields, they could be bulk copied to save time (it's ok if they visually stack when copied as long as they are different colors I can move them to the correct locations for each party manually)
