When you are entering a gift batch in RE7, a prompt arrives when you add a constituent with a recurring gift that says "this constituent has a recurring gift! Did you want to apply this gift to the recurring?". This same functionality should exist for Proposals (RE7)/ Opportunities (NXT).
If the constituent has an open Proposal with an Asked Amount (even if it doesn't match the amount of the gift), you should receive an automatic prompt to link the gift to the Proposal.
**I have also voted on and agree with the fact that the functionality of linking the gift should exist in NXT, but this functionality should exist in both!**
Agree and would add that we need the options to link to Tributes, Memberships and Events from inside a batch in the web view, just like we can in the database view.
