Yes. ASHRAE Standard 90.1, Table G3.1, No. 7 describes the conditions that must be met to allow creating a thermal block from different HVAC zones. Condition c. is "All of the zones are served by the same HVAC system or by the same kind of HVAC system."

I agree with Bill.
If you intend split the zone regardless in detailed edits, the attached illustrated guide from some time back may prove useful =).

Stephanie,
If the RTUs are identical, or at least of similar efficiency, my preference would be to combine their capacities, airflows etc. and model them as one unit/system. It is possible, but time-consuming to add zones once you have made changes in DD Edit mode. Be sure to Save-As the model to work from a new copy if you experiment with modifying the geometry/zones in DD Edit mode.
Regards,
Bill

All,
I'm needing to split one thermal zone into 2 thermal zones. Originally the whole space was to be conditioned by one rooftop unit, and now we have 2 units serving the space. Is it possible to split a space in half?
Thanks!
