Split list in the middle

Hi guys,

I want to split the outlist from the boolmask ​right through the middle.
Because both lists need to do different things.

Maybe it’s something really simple but i can’t find a solution.

List.Count node to find out how many items you have, division node to get half of that number, Math.Round node to get an integer if you had a fraction, and a List.Chop node to divide the list.
