Can't add cron job in repo Settings screen

Per the docs (https://docs.drone.io/cron/), I am trying to customize cron job schedules, but can’t find a way to do so on the Settings screen. All I have is the pre-configured ones.
I tried doing it from the command line, but the official Docker image doesn’t seem to include the drone command.

Any ideas?

Follow these instructions to download and install the CLI on your machine:
https://docs.drone.io/cli/install/
https://docs.drone.io/cli/configure/

Perfect, thanks! I didn’t even consider it’d work that way.
