Flex Cut cutting line

[SLShop]

We're currently doing a lot of flex cutting with the same designs and I'm wondering how I can use flexi to create the flex contour so that it matches exactly with the neighboring line so that it only goes up and down once. I've attached another picture to help you understands what I mean

Assuming that you're dealing with four squares and they are exactly overlaying each other on shared boundaries, weld all four together and use the result of the weld.
