Just purchased the mobile app. And I'm figuring out some of the idiosyncrasies. Overall, I like what I've seen. Regarding water, I see how to add water profiles (e.g. from my local water report) and how to select the desired profile. But I don't see functionality analogous to the desktop app which allows selecting the base profile and target profile whereby the app would calculate the required additions to reach the target profile. I only see an option to manually dnote the additions you want to make. Am I missing it or is that option not available in the mobile app. Thanks!
