Advanced Pause Menu Help

I'm trying to create a branching pause menu.

I currently have an invisible layer that contains the initial pause menu that becomes visible when the pause button is pressed and that seems to work fine, but from there I want to be able bring up a secondary menu (inventory, options, etc.).

Is there a simpler way to do this or do I need to stack more invisible layers for these sub menus?

Thanks

You can make Sprite (buttons, info, etc...) and put it outside layout, and when the game paused bring it the screen, and when the game not paused move it to outside layout.

I tried shuffling the sub menus outside of the layout and it seems to be working fine. Thanks for the help!
