[gscan2pdf-help] Right to Left arrangment with "Output pages set at 2", is it possible currently?

[Yousif AL-T. <you...@ya...>]

Hi. I'm new user for Gscan2pdf. I need to scan every 2 faced (twin) papers together per each scan process. I'm Arabic & documents that I scanning also Arabic. So, I need to set "output pages" at 2 from "clean up" option GUI dialog (window). But out put will be left half of image appear 1st & right half appear 2nd. This is O.K with Latine document, but useless with Arabic & Hebrew, because papers will be arranged as 2, 1, 4, 3, 6, 5, 8, 7, ...... So, I need to make right half on image appear 1st then followed by left half so that papers will arranged as 1, 2, 3, 4, 5, 6, 7, ......

My question: is it possible to do right to left arrangement for "output pages = 2" or not ? And if yes, so how can I achieve it ?
Best.
