The fastest way to do this is not converting it into an Enum.
You could create a Blueprint Macro Library and implement your own switch there based on a List of FName you configured in the project settings. The input being FName, the output exec pins. You can get the developer settings from BP using the “GetDefaultClass” node.
Option B is just creating an enum uasset which can easily be edited, but I have a feeling you are avoiding enum because you need a more dynamic solution.
