How to create multipage single PDF when All ArtBoards are selected using PDF create rendition?

Hi,
When i selected All ArtBoards and when i create pdf rendition. It create single page pdf document and all designs on one page which is not similar like Export --> slected/All Artborads --> Single pdf file.

Thanks
Manoj

Unfortunately the application.createRenditions() API does not support exporting multiple renditions to different pages in a single PDF file at this time.
