Custom Prices/Product Prices by UOM

It would be great if when adding custom product prices for customers that you could have price breaks as per the quantity that they purchase.

Eg. They buy 10 it is $40 per product

They buy 100 it is $35 per product

I understand you can use discounts and deals to do this however then it does not show up in the customers product prices. This means that their pricing is in 2 different areas of the system and hard to keep a track of.
