How do I set up number pad with modifier in Bartender 4?

I’ve got bar 1 set to Number Pad 0-9. For my second bar, I’m trying to use the same keys with a shift modifier, but when I do, I don’t get Shift 0, I get Insert, or Shift 9 is Page Up. I need to get rid of the Insert/Page Up/etc and make them numbers like the top row. I don’t know how to go about this, and I’d like some help, please.

Not possible. Those keys send complete different hardware events when combined with shift.

Only Num keys that can be used with shift are: 5 / * - +
