Ross:
This is possible (at least for ArchiCAD Doors, I don't know about the Cadimage door/window builder, whether it plays nice with GDL). With GDL the Story information can be requested and utilized (see
REQUEST function in the GDL Manual, page 303). This text would not be part of the ID but a separate text item added to the marker. I generally recommend taking an existing door/window marker that is close to what you want to achieve, making a copy, then editing the copy to fit your purpose. This does take GDL knowledge, and many of the ArchiCAD markers use Macros, so understanding them well enough to make non destructive edits is difficult. If you search the forum you will find advice about diving into GDL.
You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.
