A5 to A4

[marco24]

Good morning, I kindly ask the following information :

In this example I have 4 A5 sheet (my original document is 100 A5 sheet):
I'd like print first and second A5 sheet in a A4 sheet, like this: TEXT1 in the top part of the A4 sheet and TEXT2 in the bottom part of the A4 sheet, and so on, TEXT3 in the top part of the number two A4 sheet and TEXT4 in the bottom part of the number two A4 sheet and so on...

Is this possible?

Hope I explained myself.....Thanks!
