The automatisms you're aiming for depend on the host. There's no way for MIR Pro to know much about other plug-ins in Cubase, ProTools, Logic etc.. And even if there were means to establish communication between them, the data sent forwards and backwards between them would be only relevant for Vienna Instruments - a player that's hosted in VE Pro most of the time anyway. I don't think that VSL will put much effort into a solution that might be of interest for a small minority of users only.
That said, there _is_ room for enhancements in MIR Pro's preset management. I think it's safe to say that a next version of MIR will bring quite a few innovations in that respect, even ones you might like. :-)
