Loading flight plan with virtual SD Card

I would prefer to load a new flightplan in an activ airplaine - maybe with an virtual SD-Card (SD-Cardslot as Button for loading a File). That would make it possible not always going back to the world map!

This is something I expect we will see on 3rd party aircraft. It would be nice if the default Garmins had that capability. I tire of constantly re-entering FPs I use all the time.
