Ok I think that makes sense
I'll try it out
As long as they are different pages you can do that already. You would just use the page assignments. Assign one copy of the module to a specific menu item, and assign s5_tab1, 2, 3, etc. to that exact same page and only that page. Then create another copy of the tab show module and assign it to another page and because you assigned s5_tab1, 2, etc. to only specific page you can use them again for this other module. So you'll have multiple copies of the tab show and multiple modules published to s5_tab_1, 2, etc. but they will only show on the pages that they are assigned to so it won't cause any problems.
