Change filament without parking ?

Using filament ran out sensor and need to be able to change filament without nozzle parking.
I want it to lift maybe 10-20mm but keep at the last know position and resume from it without having to park X and Y.
Is this possible ?
I am printing using absolute (i think ?) position, i never home X or Y, i simply move the nozzle where i want it to start on the bed and hit print.
Of course i slice my model as close to X0 and Y0 as possible for that reason.
Why ?
Because i want to be able to control by hand exactly where print will start printing. Maybe on a small patch of tape, without having to measure where that tape is on the bed, i simply move the nozzle over it and hit print.

 

You want filament runout detection, but you don’t want the printer to park the nozzle during a change. Right？This might require trying to edit the G-code.
