Sounds like you're looking for the PageTask() function. You specify a Cicode function name, and a list of arguments to pass to the function that will associate the required tags and display the page. The benefit of using PageTask() is that it saves the function name/args in the recent pages queue, instead of just the page name. Then, if you try to browse back to a recently-displayed page, such as with the PageLast() command, it re-runs the specified function to redisplay the page with the same associations. 
 The difficult part may be to get your list of associations to fit into a single string value. For example, if your genie has metadata associations like %prefix%_prop1, %prefix%_prop2, etc., then you could change it to just pass %prefix% to a custom Cicode function, and that function would do the association of each of the properties using that prefix. 
 The association function arguments to pass to PageTask() have to be combined into a single string, with quotation marks replaced with ^". See the TaskNew() help page for an example of how to do that.
