Is there a way to only use one variable as a two-factor interaction variable

i dont want to use all class variables for interactions, I want one specific class variable to be used as an interaction variable with every other input variable.

I am talking mostly about enterprise Miner. For example, in the regression node, under the two-factor interactions option.

Is there a simple way to set this up?

Which PROC are you using? Are you using SAS EM?

EM, mostly the regression node. Edited to clarify

You need make design matrix on your own, and feed it into regression analysis.
