Dynamic Perforce Release Stream in VCS Root

Hi, I am setup using perforce streams and for dev builds we have a singular dev stream, and for pre production that also has a single preprod stream. When it comes to the release there will be a new stream for every release which will have a release name that is generated in the preprod build. So I have the preprod build setup as a dependency of the release build. And in my VCS root, the stream name that I have chosen is //com/proj/%dependnecy from preprod build release-name%.

When I try and test the connection it is reading the dependency property wrong it's getting a 2.0.0.1 where it should be a 2.0.0.217

Is there a way to fix this? I'm assuming that the VCS part of the build happens before pulling in any dependencies that's causing it?
