We are moving to an opportunity-based model, and looking at assigning prospects a fundraiser only when there is an open opportunity (and removing when the opportunity is closed out). This would be helpful to allow for a column and filter in Opp Lists of assigned fundraiser(s) to be able to make sure assignments are added/removed properly, instead of having to go into each associated record to check individually.

YES! we have different types of solicitors in our system as well, and the ability to filter by solicitor type will be extremely beneficial and allow the fundraiser to pay attention to what is needed.

We need to filter Opportunities by the Primary Fundraiser and when I go to a specific fundraiser's work center and then to Opportunities I'm seeing opportunities where they are Secondary or Executive Sponsor or Associated or otherwise connected and I need to be able to see where that fundraiser is "responsible" which is designated by the Primary filter.

This is huge for us, and is almost enough for me to want to cancel the transition from RE to RE NXT.  We have over 20,000 records, and have been using multiple solicitors (as described by the original poster) for over a decade.  If this could be fast tracked that would be incredible - it should be easy (relatively speaking of course).
