There are a few threads about this, but not one specifically requesting the change. Here’s a reply from @lubos back in 2015 answering why only ‘monthly’ is available as an option. The user wanted a daily option.
Please consider updating this feature to have additional options:
The current implementation of ‘monthly’ works, but lacks practicality for those that would rather a much shorter time frame.
Personally, I’d prefer the ‘weekly’ option the most out of what I listed above.
