No not really, each zone will need its own VRF terminal. It should be okay to model with 11 VRF terminals. It is common to do some abstraction where the modeled number of terminals is different than the actual number in the real building (though usually it works out to be fewer modeled units rather than more units the idea is the same).
As an advanced approach it would be possible to choose 4 of the largest zones and consider them "master zones" that get the VRF terminals (and good control). Then couple the remaining slave zones to a master zone with simple airflows using balanced pairs of ZoneMixing objects. The slave zones won't be under good control but their loads will get mixed into the master zone by movement of air between the spaces. The larger the airflow, the more tightly coupled the spaces will be.
