@dillonb16317612 - This has long been a challenge in Adobe Analytics, so I hope you get some traction with this request!
One suggestion I'll throw out (and others will likely offer similar thoughts) is to include the variable identifier as part of the name. Most implementations I work with use schemas similar to the following: [variableName] - [id]
For example, name your eVar "Link Destination URL - v129". If it were a prop, name it "Link Destination URL - c1" (or "p1" depending on your preference).
I recognize it's not ideal, but this makes sure you always have the identifier.
