Control Rig - Creation and reference to Procedurally generated controls

Is there a recommended or best practice for spawning items with control rig’s Construction Event and then referencing those created items in the Forward / Backward Solve?

Eg:
Construction Event - Create a Null

Forward Solve:

Set position of the Null to something else.

I’ve been doing this where I just set the reference to it, but if I change the construction name at all, this reference becomes invalid.

I am attempting to be as procedural as possible by spawning all of my controls from what’s given in the skeleton.

Any advice appreciated!
