(Edit 7/17/2014) Forgot to mention earlier: I am using ExpressionEngine, Wygwam, and Structure together.
I can set link type to "link to anchor in text"... but that's only for the current document...
Alternately I can set link type to "structure page"...
But how can I set link type to "anchor within structure page"? It's not an option, but is there a way to do it?
I know I can hardcode the link in by setting link type to "URL" and just typing it in with the #anchor at the end... but I am trying to avoid this so that the link will work in the future if I change the page name/location within structure.
