10 page DL roll fold

Hi folks, happy new year to all. We have a stahl folder, 4gates and a moveable 4gate crossfold section. We have done an 8page roll fold previously on the 1st unit using 3 of the 4gates no problem. Is it possible to do a 10page roll fold on the 1st unit using all 4gates or do we need to put the crossfold unit "inline" to do the 4th fold. The guy who used to operate the folder is off due to ill health and we're trying to cover until his return, but he's never done a 10page roll fold anyway. We've never been able to find anywhere that lists all possible folding combinations so we just try and do them as and when a job requires. many thanks for any help.
