Excluded Attribute in Analyses

I have a set of analyses, however it is possible that in certain elements some of attributes may be excluded. It appears that if an expression has an excluded attribute in it the Analysis puts off an "Error and Warnings" (Red Exclamation) for "Failed to resolve required input". Is there a way to structure the analysis to give it an 'out' for the times where an attribute is excluded? The Analysis is comprised of between 2 and 10 separate expression, and I do not want to have to break these all out into separate analyses.

 

I thought about using IF statement with TagBad()=True, but again the analysis sees the attribute as a required input it can't see.
