How to avoid or limit the under-extrusion when spool is empty and need to be changed

[Dadkitess 19]

Hi there, UMS5 user, I "like" the Flow Sensor that allow to detect under-extrusion as well as the spool being empty (same result, under to no-extrusion, obviously), even if it can be very picky and lead to false detection, but i'm here to ask if there is a way to limit the under-extrusion visible on the print, when the spool goes empty ? Like some trigger adjustment to limit the visible under extrusion ?
