Why is it not possible to use references in any of the parameters from the "Visualizer" tab of the Visualize Attribute SOP? RMB context menu offers only two options: "Revert to Previous Value" and "Revert to Defaults". Entering the reference manually via chf/chi, etc. is interpreted as plain text instead of an expression. What's so special about those parameters that referencing anything from them is impossible? Is there a workaround for that?

Just ran into this too. this has to be an oversight.

Unfortunately, they aren't parameters. That's why they can't support references. It's part of UI being cloned there instead of node parms.
