Add create w/spool to filament creation page

It would be nice if I could add a filament, and have it automatically add a spool of it at the same time. Could add a "create with spool" button in addition to the create filament, or maybe a checkbox to create a spool.

Good idea :)

+1 to this. I was thinking a create spool icon with the other icons on the filament list screen would be good. Nice quick way to create a new spool.
