I use design builder for heating and cooling design loads all the time. Yes, you can include heat recovery for both heating and cooling design.
This is done on the HVAC tab. At building level:
Go to the HVAC tab. Turn on mech vent, apply a schedule, turn on heat recovery, and apply the effectiveness. Then under the heating tab, expand sizing zone equipment, set mech vent load to 1-met by zone equipment. Ensure to uncheck "exclude heat recovery from zone heating sizing".
