Add Links into Account Tab of Menu

I'd love to be able to add Searchie pages to the Account Tab of the menu in a users hub! User case: Our payments are currently processed through wordpress. Even though I have support docs created and linked to the footer, members are missing this and are confused about where to find their payment info/upgrades/cancellations. Ideally, I'd love to be able to add a custom Searchie page under the account tab with basic info about their payments and upgrading or downgrading and then link them to their account section on Wordpress.
