Luis,
I have done this sort of thing before and it is relatively easy to accomplish in ProProgram. When I did this, I used the value of a given parameter to force ProProgram to suppress or keep active a certain feature.
Here's the way I did it:
1) Create a parameter that will logically control if you want a certain feature created. Assign it a value of 1 if you want to keep certain modeling features or 0 if you want to suppress them. Control the value of the parameter in your relations.
2) In ProProgram, scroll down to where the feature in question is created
3) At the beginning of the feature, write an 'If' statement such as:
IF FEATURE_CONTROL_PARAMETER==1
4) In ProProgram, scroll to the end of where the feature in question is created and close the IF statement with
ENDIF
5) Save and incorporate your changes and test it. This should do it.
