Is there any way to duplex print in different formats on the same piece of paper in CorelDraw?

At Christmas I create an A6 sized Christmas card - i.e. an A4 page, folded twice, to create a cover page, two interior pages, and a back page with my logo. (This year, this all prints in landscape mode.) On the reverse of the card, (so the paper has to be opened out to be read), I write a poem which fills a complete A4 page. For the last twenty years I've printed the card on one side, and then put the paper back into the printer and printed the poem out of my word processing programme. If I could duplex print the whole document from one mail merged CorelDraw file, that would save a lot of time and effort.

Is it possible?

To recap: This year the card is printed in A6 landscape, but the poem is three columns set out in portrait A4. Fiddling with the poem so it would fit into four A6 pages wouldn't be that easy.
