AOPA Real-Time FLIGHT PLANNER QUESTION

I want to create a flight plan that goes from airport A to B then to C and
back to A. The headings will change during that flight which means I have to
fly at both even+500 and odd+500 feet altitudes (VFR flight). How do I make
the flight planner reflect those altitudes in the flight log without having
to create a separate flight plan for each of the respective legs of the
flight?

Thanks for your help.
