How to move from Tabs of one Screen or more.

[N-Pu]

I have 5 tabs: TabA, TabB. TabC, TabD, TabE and in each of them there is a possibility to navigate, i.e. I have inserted Navigator inside and can open screens there. The user clicked the button on TabA and went to Screen1. I need to be able to move Screen1 from any Tab by clicking a button to TabB, not the current stack of Tabs. Pardon me if this is a strange question, but I need help with this! I tried navigating through the tabs and after opening the screen but it didn't work.

Thanks for reading.
