Multiple 890 Pro Remotes with one RF Extender

Can multiple Harmony 890 Pro remotes control a single RF extender? If so, do they share the Smart State so the equipment doesn't get stuck in funny modes with multiple remotes toggling things the wrong direction? I've read a lot of conflicting information about this on various boards.


I've got a central AV cabinet and I would rather not have multiple RF extenders ... for obvious reasons (especially Smart State).


Thanks!
