We have already implemented a "copying from another day" feature for food tracking.
We could also do it for Insulin Doses and Medications. Nevertheless, we decided not to do this.
We understand that it's inconvenient to repeatedly log the same medications, day after day, probably their long list with the same dose amounts for each drug. But, the users tend to "copy" the previous records automatically, "without thinking." Unintentional and accidental "copying" can be extremely dangerous, especially for people with a severe medical conditions. The necessity of manual input is an additional layer of verification. Security and convenience are on different scalepans. While deciding between these two, we decided on safety. We want to encourage our users to double-check each medication record and its correctness during manual input; thus, current implementation without the "copying from previous day" feature. We regret any inconvenience that this might have caused you.
