@urbanlodge I see what you are trying to do.  It looks very similar to station printing where you would have one station for fry, one for sautee, one for salad, etc. etc.  Grouping things on tickets is pickle since back in the beginning of time and it is that way across many platforms.  The easiest work around would be to have a tablet for each "station" and then have that station print only the categories you want.  So lets say you have appetizer, burgers, fries, wraps...you would need 4 tablets and have each one be a station on the kds (I forgot to mention you would have to be using square KDS for this to work)  That way you could really separate things.  With kds moving to android you should be able to do this affordably also.  But there isn't a good way to reorder items on tickets to print a certain way except to look at the all day counts for your people.
