P: change the cache storage disk

Hello. I ask you to implement a function in lightroom to change the cache storage disk (through the settings of the lightroom itself or to pull the settings from the system settings)

I also ask you to return the ability to put flags and ratings on photos shared for access and editing - this sucks, that for work you need to perform a round of saving - uploading to your new folder - putting down ratings - sharing to the same person who sent the same files. It's inconvenient for collaboration
