Pricing without adding cloud?

Setting up pricing for the clouds that are definitely going to be targets for deployments is pretty straightforward, but is there a way to check the cost against another cloud without making it available as a destination?

The use case is an environment where Morpheus is currently being configured to deploy to on-prem VMware infrastructure. Deploying to AWS is also an option, but those deployments are currently handled separately, so it would be useful to give a quick idea where a given workload would be less expensive to run (then deploy via Morpheus if the answer is vCenter).

It seems like the obvious options are to fully add the cloud or setup some sort of dummy plans on the VMware cloud that can be checked from the catalog but wouldn’t be used for actually deploying the instances. I figured it’s worth an ask if there’s anything simpler I might be missing before settling on one of these approaches.
