marketpress – user roles store settings

Some was covered here, thought I should maybe open a new thread rather than tack on.

I am using adminimize and members to restrict and enable pages and have “edit_pages” “edit_others_pages” ” edit_published_pages” enabled for Editor.

“Store settings” is the only tab option not available to the Editor.

I wish to enable “Coupons” under the “store settings” for the editor as this is important to the client to create/maintain – all the other settings in there are set and don’t require access.

Any suggestions?
