Well that is what I was thinking I could do if I have trouble keeping it in place is sew a pocket on that blue pad I bought to slip the cashel into. That is the way the pad I borrowed worked. It was a fluffy white one with a pocket that the foam pad slipped into. It wouldn't be hard to do. But I'll try it without first.

Once the saddle is cinched up it's never moved on me. It's just the storage issue that's bothered me.
The first Cashel I had, I let sit under the saddle all winter on my saddle stand, which is wood. In the spring, there was a permanent indent on the cashell from where it rested on the stand, even with only the weight of the saddle on it. So I learned from that, to save it's softness for when I'm in it.
