This can be done, but will take GDL knowledge, and this is not a beginner's task. As the referencing is complicated, it is best to start with a copy of a working Detail Marker and modifying it rather than starting from scratch. You can search this forum for other threads about this issue, it is a similar problem to creating custom Section, Elevation & Interior Elevation Markers.
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.
