P: Control over amount of smart previews stored on device

I would love more control over how much data is stored locally. Ideally a setting to keep the most recent 1,000/2,000 etc. smart previews on device. Perhaps other people would prefer an album based solution. The way the app works now, if I am not connected to the internet, it is essentially useless. Also, the speed at which smart previews load has decreased dramatically of late on my M1 iPad Pro. If my most recent images were already on device this wouldn't be an issue and the whole editing process would be so much smoother. I bought an iPad with plenty of storage. It's currently using 9GB. I'd rather it used 90GB and gave me easy access to many thousands of images.
