Only open first tab of first instance, if several tab-instances are on the same page

[max-admina]

We are using several instances of the tab-system on the same (large) page.
Atm the system opens the first tab of every instance. We'd like to tell the script to only automatically open the first tab of the first instance on the page (and not automatically open the first tabs of all other instances on that page) when the user enters the page. Is that possible?
