Cozz THIS post made it clear there is not such a node, and it would be very handy to have.
Just a node that has two spreads in and one spread out with the equal values, that works for integers, fractions and negative numbers.
Might even be nicer to be able to use the inspector to get it to work with more than 2 spreads…
Or perhaps 2 extra Output Pins with the locations off the equal slices in both spreads…
Dream dream… hehe…
