Embedded tab remote control

Hi! What's the syntax for switching tabs that are embedded in other tabs?

Let's say I have this structure:

panel 1
-tab 1
-tab 2
---panel 2
-----tab 3
-----tab 4

From tab 1, I'd like to open tab 2 in panel 1, and tab 4 in panel 2. Any easy way to do this?

Sending /TABS tab_2_id tab_4_id to o-s-c will do.

Thank you! I was sending two separate messages. Duh!
