manage scheduled tasks for multiple domains (browse credentials?)

Is it possible to manage scheduled tasks in multiple domains or forests using 9.1 ?

We have multiple domains (Test, Dev etc.) that I patch using Protect.  I can define credentials for these domains to scan and patch, however, in previous versions I could not manage scheduled tasks because the system would only use my default credentials to authenticate.  Since these credentials were for a different domain, they naturally failed.  I think this would be "browse credentials"??

I thought I saw that this problem was resolved with the current version, is this true?  Is there somewhere I need to set this up?

I also have machines and domains show up in the list that no longer exist, how can I remove these?

Thanks,

Joe
