I need to include some js file's for a few pages, I don't want to duplicate skins simply to add a js file and have more to manage or include the js file in the main skin for it to bloat every page.

So it seems to make sense to include it in a page's header from the DNN page properties. That said it'd be nice if I could then include the current CDV at the end of the file's URL to make pushing newer versions of the JS file's.

Is there a token which can be used in the page header tags for the current CDV? e.g. /this_is_the_js_file_path/js_file.js?cdv=[CURRENTCDV]?
