Folks, I don't see anyone suggesting one feature that may help here. You don't really need to create files with these CFPDF* tags if you don't want to.

For  instance, as seems Paule's issue, if one tag creates something that  then another would use (as his CFPDFFORM result then being flattened),  you can use the NAME attribute (instead of destination) to indicate a  variable to hold the output of an earlier step, and then use that  variable in the SOURCE of a later step.
