Being able to add an appeal to a proposal would actually be more helpful to us than only allowing a proposal to be associated with a campaign or a fund.
In some cases, we might want to see what proposals exist for a specific appeal (which happens more often than not), but there's no way to add that to a proposal. It seems like a very obvious missing feature, especially since you can associate a campaign and a fund with a proposal.
This will be super helpful to query off of proposals for a particular event which is identified by the appeal. It would unify the projections with the funds that have already come in for these various events and appeals.
Ditto for actions
