Add Creo model parameter values as suffix to published additional files thru xml

Is there a way to modify the additional files published names by using model parameters (like revision, or version, for example) as a suffix? 

What I'd like to do is something like this:

<publish on="create-representation" display-label="Publish w/ additional files" additional-files="dump_to_all" output-suffix=">{revision parameter} </> but as another post noted, the keys aren't available.
