'easy Blogging - marketpress - fields

Multisite install.
Stores all with the same appearance etc .
Force easy blogging
however for Marketpress we would like the store owners to be able to use some - not all store settings.

ie Setup taxes and coupons but not change payments and shortcodes etc.

Using the custom url types displays the entire store settings options not each one.

Am unable to see how to achieve this, is it possible under the current setup using WPMU?

Thanks again.
