Question about printing

I was wondering if there was a way to print the first 4 pages in duplex (so it is on both sides of the paper) and the last 3 pages on simplex (so 1 site per paper). 

I can't split it up into 2 pdf files, because I have to print these 5 pages (because of the double printed one) in a large number in the correct order, otherwise it is too much effort for me to do it manually. 

Is there any advice?

Thanks
