Issue 1 : Batch print window freezes when i try to delete layout files and only try to print Model files of my .dwg drawings i.e I tried selecting like 14 .dwg files which had both (model +layout) files in it and deleted all the layout files so that i could print only model files but in the process of deleting Layout when i delete the last Layout my window freezes as shown in below pic

Issue2 : How can i print all my .dwg files into a single PDF. I think this feature would be very helpful as AUTOCAD has an option to do it. I can export them into individual pdf files but not into a single PDF.
