Choose sheet size and other properties when creating pdfs from jpeg

Hello,

I think that the possibility to choose sheet size and other properties when creating pdfs from jpeg is missing. It is nice to be able to combine several jpegs to a pdf by the "combine function", but unfortunately, this creates huge sheets of the jpegs as opposed to the regular A4. 

I had to go into each jpeg and print them from "windows photo", and that should be unnecessary. Maybe I am overlooking a solution, if not, this function should be added.
