Driud/Warrior Stance/Form addon that let's you assign more bars when switching.

Hi
I'd like to start off by saying that I'm not a native english speaker so I appologise for all gramma/spelling mistakes.

I'm searching for an addon that allows me to assign more than just one bar to switch when I change stance/form.
Normally when you play as druid or warrior when you switch stance only bar 1 changes and allows you to assign diffrent spells to it and it can be switched so that you have entirely diffrent spells on each form/stance. Now my question is: Is there an addon that would allow me to switch also bars like bar 2 on form switches. That way i could have 2 bars that are consisten across all forms/stances and 2 bars that switch.

If it's also compatible with Elvui that would be amazing.

Thanks in advance.

Use Action Paging on the ActionBars:
Stance 1 stands for Page 7 and so on, you got 9 Pages and all Bars share those, but at least you could if you dont use all 6 Bars use it's page for one stance.

Also there is a additional Plugin to ElvUI:
ElvUI_ExtraActionBars: https://github.com/ElvUI-WotLK/ElvUI_ExtraActionBars
Not sure what that does.

hope this helps, it not completly resolving your issue.
