Like all DOE-2 based programs, EE4 is limited to 1 system serving a zone.
That said, what you are describing sounds like a packaged VAV system with
zonal heating and/or reheat. The issue seems to be the "main system"
which sounds like a make-up air unit which you would have to work into the
PVAV for fan energy and heat recovery (if applicable).
