Wind Variations Using Wind Directional Source

Hey everyone.

I’ve made a blowing curtain using a Skeletal Mesh with Cloth Painting and a Wind Directional Source. I’m happy with how it looks when it’s blowing but I’m finding the problem to be variation.

I’d like it to occasionally return to the original position shown in the first image below (as if no wind is blowing)


. I’ve played around with the Speed, Strength and Gust amounts but no luck.

Any ideas please?
Thanks in advance.
