Forgot to start timelapse

Can I start a timelapse once a print is already started ?

I have just started using OctoPi with my Creality Ender 3.
It prints via USB OK. The USB webcam connected to the OctoPi shows the activity.
But I forgot to set the Timelapse Mode default to ON to automatically start a timelapse when a print starts.

Can I start a timelapse once a print is already started ?

Octoprint 1.5.2 OctoPi 0.17.0
