Allow full URLs to be opened in specific containers

[djhworld]

At work I login to my cloud provider accounts through a federated login, e.g.

For my development environment: https://federated-login-service.foo/cloud/account/development
For my production environment: https://federated-login-service.foo/cloud/account/production

If I create two profiles in Multi Account Containers (e.g. "Dev", "Prod") I can't see a way of assigning the above URLs to each container profile, so they open in the correct one.

e.g.

if I visit the development URL, it should always open in my "Dev" container profile
if I visit the production URL, it should always open in my "Prod" container profile

When I tick the 'Always open in....' checkbox, it doesn't seem to work this way, it looks like it works at the domain level (i.e. federated-login-service.foo) rather than the above case where the URL implies different semantics.
