Adding Connections Directly to Resources

[dinaherbert]

Is your feature request related to a problem? Please describe.
It would be great to be able to add CPF links directly to the resource pages. It would save editors a lot of time when adding in new finding aid links and also possibly help with the ingest of new materials.

Describe the solution you'd like
I'd love a button, similar to the Holding Repository Search, in the resources edit page (from the other entities/manage resources dash) to link finding aids directly to related CPFs.

Describe alternatives you've considered
Right now, it's cumbersome to add all the additional CPFs found in a finding aid (especially for the really well processed collections!): an editor has to go into each individual constellation.

There would, obviously, be some issues. If a constellation didn't exist in SNAC for a CPF an editor would have to "bookmark" it and create a new constellation and then still add the resource & its relationship (referencedIn, creatorOf). For records that need merging this would be another consideration, although you already have to consider this for merging in general. I just think this would save a great deal (really, a great deal!) of time and also encourage editors to edit directly in the manage resources pages. That could be helpful as we update worldcat links or make something DigitalArchivalResources, etc.

Additional context
Here are some examples that came up when I was editing Mary Watson Whitney's record earlier.

I edited a broken link to Maria Mitchell's papers at Vassar College.

SNAC resource Page

There are 5 CPF relations for this collection.

If you look at the Vassar Finding Aid, you'll see there are WAY more than 5 CPF relations.

And several of these CPFs are in SNAC (example: Oliver, James Edward 1829-1895, Taylor, James Monroe, 1848-1916, Vassar College. Observatory) Although this isn't the best example; there are links to most of these through some dead WorldCat links for Mitchell's papers, but you get the idea.

If there was a search similar to the holdings institution for connections that would be great.

If could just reverse what we do with the add resource in the individual constellation page
