Diversions

Any chance the FAA can give better diversion information to FA?
So far this morning 4 flights have diverted from KSMX to KSBP due to fog. Since both airports are under the same approach control FA does not receive this information.

These are IFR flights, so the information should be in the system somewhere. I know this has been asked before, but it seems like it should be fairly simple (or not) to do.
