Option to force filament selection prior to print

[alweekes]

Describe the solution you'd like
I've been using this plugin for many years, but very frequently forget to select the filament prior to a print, which then puts the data in relation to the amounts of filament left on a reel out of kilter.

I'd love an option to force the selection of filament type when hitting print, or loading an stl file, to act as a reminder to choose the filament.

It should be an option for those that don't want the neg of a pop-up
