I would like to see this, too. I am new to jobs by tag, but I envisioned setting up something like:
One policy might be "Ops VMs in AAA with 12h RPO". To create a job to match that, I would LIKE to select the tags Ops AND AAA AND 12h. However, selecting those three gives Ops OR AAA OR 12h, which matches the wrong set. Instead, I've defined a single tag category with a few tags underneath:
I can then create a job matching the tag Ops12h and exclude the datacenter objects for BBB and CCC, then another one that excludes AAA and CCC, etc. That works, but seems less than ideal, esp if we add another DC in the future. I'll have to touch every job to add exclusion, or create even more tags that are locked down to each datacenter, etc.
