Ability to Cancel an Object prior to starting a print

[BrienKing]

I currently have a object that I print 9 at a time, however sometimes I don't need that many and the number I need can vary from job to job.

It would be nice to have a feature that allows me to cancel objects even before the print starts.

Scenarios might be
I only need 3 of the 9 printed so I cancel 6 of them.
I only have X amount of filament left and I know I can get 4 done but not 9, so I could cancel 5 of them.
I only need 1 more (to make 10) so I cancel 8 of them.

This would keep me from having to slice 9 different versions if any changes happened to the object or settings, having to update 9 projects and re-slice them.

Hello @BrienKing , is there a reason why starting the print a immediately canceling some of the objects does not work for you?

Yes, the print takes about 20 minutes to start. I'm printing a full bed of ABS so I have to wait for the bed to get to 100C, the Nozzle to get to 170C, wait 11 minutes for the bed to absorb heat, then probe 144 points, wait for the extruder to get to 245C and then it starts to print.

Normally I just click "Go" and walk away. If I have to wait to cancel parts of my job that means I have to sit there and watch it for 20 minutes or hope I can get back to it in just the right time to cancel the parts without it starting them.
