[Request] Material Editor: Right click > change Add to Multiply

As someone who spends a lot of time in the Material editor I tend to try a lot of different combinations.
One of the things I try out the most is the difference Add and Multiply to see their results.

would it be possible to have a rightclick > change to X that replaced Add with Multiply and vice versa?
I am sure there are other rightclick > replace features people would like, but this is the one that I personally would use a lot.

Additional comment/request:
Rightclick change panner to rotator and vice versa.

for the “blend_” options, have a dropdown menu you can change just as in photoshop, so press down/up and you change from Blend_ColorDodge to Blend_Darken (or when pressing up to Blend_ColorBurn)
Would save a lot of time.

Another way to do this, is (and LittleBigPlanet) is a good example.
If I move “ADD” over “Multiply” while holding i.e. Shift (and/or) alt itll replace Multiply with ADD.
