Tabs using Panels and in Panels

Hello there,
I searched the forum and even posted one forum topic too, but neither found any fruitfull information nor I got response of the post, which is why I'm posting this here.

I have two secondary tabs created with Panels and for those secondaries I have one primary local task which is default local task too.
Now, I want another Primary local task with no children.

I tried hard, also with hacking the code, but could not do that.

Has any one here any idea for this?

Thank you.
