Just a thought - could you try instead of deactivating them just moving them to low level - that would make it so they weren't listed as PROVIDER when it comes to check on number of providers you have in AC, but not delete any thing from the past.
Locums here - full provider, after they leave move them to lower level, but not deactivate. If same provider comes for another stint - up their level again.
Just trying to find a workaround that would work.
