Ignore URLs open in a certain (e.g. temporary) container

This would allow for much smoother cooperation with Temporary Containers.

Since those containers are, well, temporary, the only way I can think of is to check the name of a container in which the page is open, and if it matches a pattern (e.g. "Temporary Container 1"), ignore it. This would let me open a site which I normally want locked to a specific container in a different one, without launching an entire private window.
