In Print Organizer we can create fences for the export from shapes on a certain level and then the content of these shapes gets written into separate pages in the PDF or even separate PDF files.

I would like to do the same for DWG export.

(I know we could create separate sheet models in the DGN and then export these to separate DWGs, but I want to skip this step. For us it is comfortable to draw all sheets in one model. For PDF creation we use shapes to define the sheets. When a client wants to have separate DWGs for every sheet we export via selection set at the moment, but would be nice to have it as a batch process like print organizer does it for PDFs.)
