Vacuum has not been emptied in X days notification

My robot vacuum gets full every 3 days, but being a human and not a robot I often forget which day it needs to be emptied. The vacuum has a sensor that knows when the lid is opened.

I would like to see an option in the app that lets me pick a number of days since lid was opened notification

“Number of days since the lid was opened”: 3
This would warn me before starting a vacuum run after 3 days when the lid has not been opened:
“Vacuum has not been emptied in 3 Days, do you want to continue?”
This would also be a great benefit for when people go on vacation
