Dynamically choose branch when building repo in Bamboo.

[Justin_Doe]

Within Bamboo I have several linked repositories. Each one of these repositories are connected to a specific branch, which you have to set through Bamboo's web interface. Is it possible to dynamically choose the branch without having to go in and change the linked repo branch every single time? Is there anything in the REST API that handles this?

For example, if I run a script with a "branchName" value, I would want Bamboo to change the linked repo's branch to whatever "branchName" is.
