Yes, you can use substitutions in your Joomla menu items to CBs profile page (note this only works for CB menu items). Alternatively you can use CB Auto Actions to insert custom header data on any trigger you like. Profiles already have an h3 heading (their profile name). You shouldn't need an h1 heading as that's typically what should be around your site name at the top of the page. At any rate you can add whatever heading you like at the top of the profile using a Custom HTML field on a tab in the Header tab position.
