Having the same printer I know what you mean. Problem is that printer buffers moves so we never know where it currently is. To be able to do so we would need to change layer go to y = 130 maybe, wait for all moves to end, add 10 G4 P1 and then a go relative extrusion, extrude a tiny bit and go to absolute extrusion mode back. As you can guess this is not good quality wise for the print, but if you add this in the after layer change of your slicer it would work.
If you have a better, meaning less intrusive idea to have a special position without disturbing print please let me know. Would solve the timelapse problem for a lot of printers.
