Calibration of multiple devices

Hi all, I am using Audiomoth for the first time. I will be projecting known pure tones and frog vocalisations and measuring the loudness across an array of Audiomoths. Does anybody have a method for calibrating multiple Audiomoths at once?

If not, I will probably be looking at developing a standard method/set up and could post here if anybody else is interested?

Cheers!
