I think you would need to import the dwg and image files into archicad, place them in the detail windows you created with the markers, save views of those detail windows(layer comb, scale, disp. options) and import those views to plotmaker. You could of course create an empty detail window (tied to a marker), save a view of the empty window, and import to the same sheet and location that you have your dwg and image files. That of course defeats part of the purpose of auto labeling since you would have to move both placed drawings (ie dwg and imported view) to have things update correctly.
