Not sure if this is possible or not but can you have a Template value set as the category. Simple testing (MW 1.21) seems to indicate not but is there a special format to do this that I have been unable to locate?
Any help is much appreciated - even a nope it can't be done.
eg On entry page in edit mode
{{Example Template |name= |number= }}
Template:Example Template page Name:{{{name}}}<br> Number:{{{number}}}<br> [[Category:{{{name}}}]]
Thanks
