Additions were made to the itinerary for 2014, with races in New Jersey and Mexico provisionally introduced, subject to confirmation in December.
Michael told Autosport that teams may be forced into employing people specifically to set up teams at a Grand Prix rather than utilising the race crew in that capacity.
He said: "I guess anything is possible; we just need to adapt if that is what is required.
"F1 is all about change. I've been through plenty of examples previously in my F1 career where I've thought 'there is no way they can do that', and they do."
F1 teams will be returning to race at the rebranded Red Bull Ring, which last hosted a Grand Prix in 2004.
