Reuse existing container with new tab

[Snake883]

I want to reuse an existing container based on the domain name (or subdomain). The main reason why I want this option is because I am logged into a site, I want to use multiple tabs, and they need to be in the same container (because of my logged-in session).

For example:

I have a tab open for https://forum.me.com (container=tmp1). I am logged into "forum.me.com", therefore have a session. I open a new tab. I paste the URL "https://forum.me.com" and go. I don't want a new container tmp2. I want to reuse the container tmp1.

For this use case I'd recommend a permanent container Add-on like Multi-Account Containers or Containerise. However, I can see how such preference would be helpful and would be open to review a PR introducing it.
