How to push a page onto a tab from the sidemenu?

So I have a working Tabs + Sidemenu Application. (Works like in this example).

But now I want to push a page on top of a tab page, but from the sidemenu.
I want it to be just as if I pushed it from the specific tab page, no disappearing tabs and a back button leading to the tab page again.


How can I do this?

Any help is appreciated, thanks :):duck:
