Move Active Window Relative to Current Position

Hello. Firstly, I just recently discovered this app and am a huge fan!

One thing I've been trying to accomplish is simply "nudging" a window 5-10px up/down/left/right relative to the windows current position. Does anyone know if this possible? I've seen that I can move the window relative to an absolute position on the screen, but not relative to its current position.

Any help is appreciated. Thanks!
