Changing the Admin Tabs in Marketpress

This is a repeat question that was never resolved by another member of WPMU.... "Hi, it will be nice if super admins have the ability to hide some tabs that show in store settings from admins. Eg, themes that show in presentation tab for branding purposes. Right now I am deleting tabs from marketpress.php but they get wiped out with upgrades. I can use menu editor to hide dashboard items that appear on the left navigation panel of the admin bar but haven;t figured out an easy way to hide tabs like those in the Marketpress image below...."

Thanks,
Jafar
