Here's how @StephenHeaps is planning to do it in iOS by reusing the sign request panels. This seems like a reasonable approach here as well:

I am following this issue, but if core support is added for storing the custom recipient on CoW Swap transactions then iOS will need an update as well to pass the custom recipient address to the safer sign UI. 🙂
