This is just something I thought of during your presentation to MM SIG. We are a consortium where we have 6 OCLC accounts, one for each school and one for our depository. We are migrating to a single instance of FOLIO where we are sharing srs and instance records. An institution can add a holdings to an instance already there because they now have that resource. What we have been doing until recently was to add a 938 to our MARC bib records that triggered an action to set/remove holdings in OCLC and then remove the 938 so it wouldn't be picked up again. We stopped this because we just weren't sure how to do this in FOLIO.
If there is no 938 trigger, you would have to use a trigger for new instances and their holdings, and newly created holdings since we share bibs. This seems rather complex.
