How to create custom enum attribute that can be read in the bifrost graph?

[mcw0]

OK, I thought I had the solution with "addAttr".  That creates the attribute.  But I can't access it in the graph.

I want to add a "method" attribute to my bifrostGraph node with "Inward", "Outward" and "Bidirectional" as options.  But when I create a "value" node, under the "enum" option are only predefined values.  And "Custom" isn't custom at all.  Or at least I'm not making sense of how to use it.  How do I create my own?
