Thank you for reporting. I'm not sure I understand completely and just thinking aloud so feel free to correct me. Of course Stefan is invited to chip in too.

So basically we have the structure: Place -> Stratigraphic unit -> Feature -> Find/Human Remains

• you are at a strategraphic unit and want to link an existing reference
• in the list of available references you would like already linked ones to the place on top

• there is no "main source" for a site, there can be multiple references and all are equal
• by the same logic if you are at e.g. a find, all references from above (Feature, Strat. Unit, Place) would have to show on top of the list too

• you are at a strategraphic unit and want to link an existing reference
• at the add reference table you type e.g. oben in the search filter field above and select Obenaus 2010 from the 3 displayed ones

Is this correct so far or did I misunderstand or missed something?

I think this could be (from a conceptual point of view) achieved by differentiating between primary and secondary (bibliographical) sources in the reference.
The link between the entity and the reference could be linked to a type ("primary" or "secondary") to state that one reference is the main source and the others are further bibliography entries. When adding a new reference to the subunits or to images that are attached to them this main source could somehow be suggested more prominent so it would be easier to select the right reference.

Hope this is in some way, what Nina wanted to have?
best, Stefan
