@Farmer-Ed I’d be happy to help you through the process of a contrib module implementation if you’re interested in going down that route! Similar to the process @jgOhYeah and I went through in Is it possible to use custom fields and filtering in asset views and filter by a range of birth dates?
Happy to do that here or in a separate dedicated thread, if that would make more sense (keep this one general)?
First thing I would do is point to some of the other examples of entity event subscribers…
