Purchased Price - Custom Keyboard Hot Key?

I work with lots of purchased items. I see the SolidWorks Costing feature but that is overkill for my application. I was wondering what is the easiest way to:

1) Assign a purchased price to a part

2) Link this to a keyboard short cut so that I can enter it easily without having to go into custom properties every time.

Is there an easy way to do this?

Thank you!
