P: Saving custom file export name

I really love the custom naming scheme on file export, and I use it often. However my custom naming scheme depends on the situation, and I currently have half a dozen regularly used file naming schemes. I don't really like to have to look up the naming scheme each time and then reconstruct it because it was different from the previously used one. It would be great to to be able to save a naming scheme and then select for reuse!

(oh, and this interface needs many feature requests! For example I am forced to select one of four topics before proceeding with no option to change. None of the four apply. I came accross half a dozen usability issues on the way to this form. From someone else, OK, but from the vendor of usability products????)
