Hot to start printing automatically after Gcode file upload?

Hello!

Is it possible to start printing automatically after Gcode file upload into the "watched" folder? I see how the file moved to the "uploads" folder, but I don't know how to force OctoPrint to print this file automatically. I had to open OctoPrint and press "Print" button every time, manually.

I tried to use the Autoselect plugin, but of course it only select last uploaded file and don't start printing (as expected).

Was OctoPrint 1.3.8 running on OctoPi 0.15.1,
now OctoPrint 1.3.9 running on OctoPi 0.15.1

Thanks!
