Print Booklet - Double Sided - Indesign CC - Aaarrrggghh!!

Hello,

Could someone please share with me, as to how I can go about printing a double sided booklet under the 'Print Booklet' option in ID CC??

There are collation options, but not an option to print 'Odd Pages' and 'Even Pages' separately.

I am using 'legal size - half', so 4 pages per sheet, double sided.

Thanks in advance,

Derek
