Using P&D to deploy a SmartForm into an environment with multiple templates - how does it know which one will have its value?

I'm setting a value in the environment table for a SharePoint URL for the Work List in my Provisioning project.  There is also an EDM project in K2 that has its own environment template. 

When I move from DEV to QA how can I tell the form to look into the template for the provisioning project for the Work List URL?  The EDM environment template won't contain the value.

When I deploy the process I tell MSBUILD what template to grab, how do you do that with Forms?

It looks like the environment template you want to use may have to be set as default when you deploy - is this the case?
