HowTo: Alter Deployment Constraint Tags in a pre-provisioning subscription

[Tocano]

We have a CloudTemplate catalog item with a pre-provisioning subscription (EventTopic: Deployment Requested) which kicks off an Orchestrator workflow where we run some business logic before the VM is created. In certain circumstances, we want to change/override/modify the resource constraint tags that AA uses for the provisioning. 

I have the workflow kicking off where I want. I have the logic in the workflow working as desired. It catches the condition case we're looking for. But I haven't been able to figure out how to modify the constraint tags so that it provisions as we want it to.

Any help or nudge in the right direction would be appreciated. 

Thanks

As far as I know, the placement is the very first thing that vRA does when submit a Cloud Template, therefore it doesn't matter what changes you make to tags in a subscription, the placement will not change.
