reload program through pin

is it possible to reload the current program through a hal pin?

i'm building a sort of pendant which includes a button for touching off the current axis. the touch-off works however unless the program is reloaded the backplot does not reflect the offset properly. and the only solution I found is to reload program (I guess that's what the touchoff button in axis does?)

or is there some other way to update the backplot?

thanks

looks like its not that simple. ill have a deeper look into this, at least now i know what i'm looking for. will feedback once i get some reaults (or get stuck somewhere )
