Display message before print start?

Is there a way to have Octoprint display a reminder message before the start of a print?

What is the problem?

What did you already try to solve it?

Logs (octoprint.log, serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support!)

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible)

What kind of reminder? Like a confirmation prompt before continuing or just a notice that it is happening?

A confirmation prompt before continuing.

There appears to be a setting for that...

Actually I meant with a custom message to remind me to do something before the print starts.

Just an idea

What about this and this?

You could put them at the top of your start gcode (or use them as start gcode in octoprint which will do the same thing).
Then you get a beep + message on your printers display and it's some time before the print starts because it has to heat up after the message.

If you want it to wait for confirmation you could also add M0 or M226 but I have not tested them and I'm not sure how they work.
