I'm creating a form with a sublist in a suitelet. How do I set the default sort column/field? RIght now its just sorting by the last field

I had the same issue recently. I can't remember the logic but I think it sorts by the first numeric field

Ah, yeah i need to sort by a date column. Realized that it does keep the original order i add the lines though, but yep, the sort arrow is always on the last column for me as well
