How do you manage Scrum Teams in Octane?

Hello everyone,

we have Scrum Teams, each working on more than one application.

Today we have a single Workspace. Would you say that is a good fit or should we use one Workspace for each team?

Because the problem is that we can't work with releases because sprints are tied to releases.

How do you manage short releases? Suppose a release is not much longer than a sprint. Or maybe a team is working on more than one application. You wouldn't see all the user stories because you have to select a release to be able to select sprints.

How about release processes? Would this be an alternative to planning independent releases for a Scrum team working on more than one application? But it seems that only the Admins are able to set up a release process.
