Deployment - Ability to set injected at the build time variable as a Release Version

Scenario:
1. Bamboo build produces artifacts and generates a custom software version as a combination of our string and ${bamboo.BuildNumber}  - in this scenario we generate a Microsoft-like version, e.g. 21.1.21.43 - (1.jpg attached)
2. Use Bamboo "Inject Variable" plugin to inject this version into build results (1.jpg attached)
3. Enable the Deployment Project to use this ${bamboo.inject.myVariable} to set as a Release Version (2.jpg) - currently it doesn't understand this variable. (3.jpg attached)
