Well...
Sort of.
You can set the values of the strings (Text2) to the auto-text names used by PlotMaker (such as <CLIENTNAME>, <DRAWINGNAME>, etc.). This will pick up the value when the drawing is placed in a layout. As I think about it, this is probably what you were looking for (more or less).
There is no (simple) way to read the info back into ArchiCAD.
