Parts Matrix Setting that allows system to use the greater of MSRP or Matrix price

We sell a lot of aftermarket parts (being a non-OEM store) so we use a pricing matrix. Often most of our parts matrix prices over MSRP (good!), but sometimes an aftermarket part can be significantly less than retail. Say a control arm MSRP is $600 but we can get aftermarket for $95. Our matrix may sell this for $300, and to sell for $600 we need to manually override this price. It would be helpful if there was a setting, or a flag, to allow the system to choose the greater of either the matrix calculated price or MSRP, to help maximize GP on all parts! M3!!!
