UDTs/GCBs in MenuManager?

[appleyard]

Is it not possible to use user defined tags or global content blocks (or, I guess, any Smarty tags) in Menu Manager?

I'm creating a portfolio site that uses a jQuery slider to navigate between content panels, so technically all the content is on one page. To make it easier on others in my company who will be helping manage content, I have created separate content pages for each portfolio item and use Menu Manager with CG Simple Smarty to put them all together with the jQuery slider. It's actually a great system, but I noticed that my {youtube} UDT wasn't rendering. I tried a Global Content Block and the {mailto} tag, but they didn't work either. I guess it's because Menu Manager is called after the UDTs and other Smarty tags are rendered, but is there any way to change this?

Thanks!
