XY point of origin

[Justanamelessguy]

So, I've been trying to get the dji Tello drone to follow a set list of coordinates but apparently the point of origin xy(0,0) resets after every go to xy command. And since I don't have the nerves to calculate each coordinate from a new point of origin every time I'm asking if someone knows how to change the value of the point of origin or takeoff location, so that I can set a fixed coordinate as point of origin for the entire flight.
