How to override variables when creating a plan branch via API?

[Chris Brown]

I see from the API docs that I can create a plan branch from an existing plan using this API call:
https://docs.atlassian.com/bamboo/REST/5.14.0/#d2e443

However, it doesn't seem like I am able to set plan variables for that branch. In addition there are a bunch of other things I can't set, like the schedule.

I'm aware that I can set custom variables using this API: https://docs.atlassian.com/bamboo/REST/5.14.0/#d2e954

However, that API call is only for individual builds, not for an entire plan branch. I have a plan that I'd like to create plan branches for programmatically, overring custom variables for each plan, and setting the new plan branches to run nightly. Is this possible with the REST api?

Did you ever figure something out for this? I'm looking for the same info. Thanks.
