[FEAT]: Dynamic window_container_behaviour support?

[Jaehaks]

Is your feature request related to a problem? Please describe.
I like Vertical Stack layout for work, but it makes the additional window too small if I set window_container_behaviour is "Create" .
When I set window_container_behaviour to "Append", it stacks with full screen at initiation

Describe the solution you'd like
As dynamic layout switching, Can I set dynamic window_container_behaviour depending on the number of window?

For example, When I set Vertical Stack,
the new window attached with the rule of "Create" window_container_behaviour until 3 windows.
After than, the window_container_behaviour changes to "Append"
