Bamboo plan branch creation with multiple repos

[sunil jaiswal]

I want to create a bamboo plan with two repos linked to it. Now I want it to configure in such a manner that the bamboo plan branch should be created whenever I create a branch in repoA or repoB with regex like release_1_x_x.
FYI: I Know we can config in the plan "Create plan branch" section that regex and it will automatically create the bamboo plan branch.

But my question is if I have two repos then that plan branch should be created when we create the vcs in any repos.
