multi level price select

In some clients i change they price depending of some conditions.
So i have made 4 price levels to every product with different prices.
Any time i have a new order i go to the client and i change the price
level depending of the conditions.

It will be very nice if i could create a new order and when i insert a new product
in the price column it will be a combo box showing the 4 prices of the product
and i could select the one i want.

Thank you.

Or if I could select more than one price level on the client

I take a look at the module but it want do that i want.
