n1 and n2 can be added to existing popup UI, while n3 would require something new.
One limitation with n1 idea is that the permanent container name should be a completely new container - there is no concept of "merging" containers, you can only rename them. So even if you renamed the current temp container to the same name as an existing permanent container, you just end up with 2 separate containers with the same name with no real way to differentiate between them.
