How to generate PDF files with GeneXus with leaves of different orientation (portrait and landscape)?

To achieve this we can use an excellent contribution by Luciano Silveira and Martin Olivieri published in GeneXus marketplace, it is the external object called PDF Tools. Once generated PDF files, you must use the ConcatFiles method to generate a new file containing the above and can thus be achieved in a single file portrait and landscape sheets.

Another alternative, is indicated in the SAC # 22611 PDF Reports chained, chained there explained as PDF reports without using external objects, but here I could not interleaves with different orientation.
