Product Pricing Calculator Permission Allow Arbitrary based on Site Group.

Ability to assign "Allow Arbitrary Quantities" at product level by Site Group, not just Q1, Q2 etc.. All our sites require limits for the Regular User group with dropdown choices, such as 5,10,15 qty only. BUT the Admin/Site Owner group needs to be able to order any quantity thus needing Allow Arbitrary Quantities to do so. Creating a calculator from 5 to 5000 as a dropdown just isn't efficient for us or the Client Site Owner. Especially across thousands of Products.
