How to use analisys set in Forecast Profile (inside plan)

Summary:

Content (required):

I would like to know if it is possible to use a analysis set that separate by demand class to 
associate with the statistical profile. 
For example: I have item 123, where the history was divided into two classes, X and Y. 
For item 123 with class X I want to run a statistical profile with the linear regression model 
and the same item with class Y I want to run with a profile that does not have linear regression. 
It is possible?
