How put an Hold on the active flight plan.Garmin g1000 c172sp carenado and phantom 300 carenado

how import and save flight plan on the same airplanes

thank you

To answer your question, I don't think that's possible in the Carenado birds. You might try saving a default flight plan and then loading it, but I haven't tried on my end. Holds are certainly not a possibility unless hand flown in the Carenado birds.
