You can kludge this now, see Alex's tip at

. But clearly this should be possible entirely within ArchiCAD. Auto text is creeping it's way into other tools (check out the little pull downs when you select the text in a level or elevation dimension). Your suggestion is one of the most useful and is needed to close the loop now that we have titles and auto-numbering in PM.

Yes, you read that correctly, we are in the US but use the INT version, because the libraries are better.
