FIX equivalent of using crossdimensional operators

Hi all,

This is doubt I have always had and now I'm facing a situation where doing this would be very useful.

As you know, you cannot use a crossdim in a FIX, like

FIX (mbrDim1->mbrDim2)

Calcs;

ENDFIX

So what can be used as a workaround instead?

My current calc goes like:

FIX(Scenario1, Scenario2, Version1, Version2)

Large calcs here;

ENDFIX

But the data I want to calculate resides in Scenario1->Version1 and in Scenario2->Version2. Any other combination must be kept out of the calc. The only solution I can see is

FIX(Scenario1, Version1)
