Suggestion for improving the YAZIO app

Currently, it's not very user-friendly to log water intake from containers of various sizes, like water bottles, as the predefined options for water volume are limited (e.g., small glass, big glass). To change the volume, a user has to go deep into the settings, which is inconvenient, especially when logging water multiple times a day.
I propose adding a feature that allows users to manually input a specific volume (in ml or oz) directly from the main water logging screen. This would make the process much more flexible and efficient for users who drink from various containers or don't know the exact volume of their glass.
Alternatively, providing a quick-access option on the main screen to change the default volume would also be a great improvement.
Thank you for considering this feedback. I believe this small change would significantly enhance the user experience.
