Inventory kits, show sale price on item lines?


I’m starting to use inventory kits for sales items. This works like an assembly meaning i can put the inventory kit code on my invoice and inventory of the various items gets updated correctly.
One thing i wish for is a way for manager to calculate the sales price of the inventory kit based on the items in it.
Currently item lines on inventory kits show just item code and quantity. Would it be possible to have a price column added and a running calculation of the total on the bottom? You could also have a check box that if checked takes the total and inserts it into the sales price field on the inventory kit.

Any thoughts?
