Feature request: multiple tree publishing from behaviortree cpp to groot 2 on the same port

[marmik18]

I would request multiple tree publishing from behaviortree cpp to groot 2 on the same port. For example, I have an initializing sequence tree which when returns a success i move ahead with by ticking main tree. Please let me know if this is a bad design.

Alternatives Publishing on 2 different ports. But this isn't a good idea because we could have multiple devices running trees and having 1 port for 1 complete lifecycle of the robot would be better.
