I second this idea! I actually have a post on makerworld for addressing this issue → G-code to clean nozzle after print ends (X1/P1) by Kehali Woldemichael - MakerWorld.
Essentially, I modified the machine end gcode to have the printer pause while over poop chute to allow leftover filament to ooze. Then wipe. Lower temp to 140 and wipe again.
There is another post here that talks about something similar → How to add extra nozzle wipe after finishing printing with PETG - #11 by yehor.
