I'm working on a site right now that wants to have a service fee added on a per attribute basis rather than order / quantity. When I add multiple attribute quantities (not using the attribute quantities module) and because the quantity is set to 1 (a neccessary part of this site setup) the fee is only added once.

Test case:

1 quantity selected (the product)
Buying 3 red
Buying 2 black

Fee of 1.50 gets added to the whole order but it should be added 5 times (e.g. 1.50 x 5 = 7.50). Is there someway to do this?
