Send multiple pages to cutter

My client is using CorelDRAW with a Summa WinPlot plugin.

He has multiple pages, that he would like to send to the WinPlot in order to cut it. But it seems we can only send one at a time from CorelDRAW to WinPlot

Please see this 18 sec video:

s you can see, having imported that many pages, it would be nice to send at once. Or import directly to Winplot. Or merge them all somehow in CorelDRAW before sending. Or...

Thank you in advance!
