the exp bar switch between tradeskill and adventurer seems to be hardcoded from what i have seen when i was doing my exp bar for the test server. If you DO have the default names for the 2 pages for the ts/adv exp only 1 at a time will show and you have to use the right click -> switch to adv/ts experience, BUT if you just rename the pages then they both show up, however maybe that was just something strange for me. If it is hard coded you could always use a button toggle that makes it hide one page with the exp bar and show the other and then set itself so that when its clicked again to do the opposite. <---- really long run on sentance, sorry about that
