Multi-criteria avarage review stars to SERP

Hello,
I have a high school review site where I use Multi-criteria based rating system.

I would like to ask if it is possible to put the results of the average of this review into Google results. From the instructions of the plugin, it seems to me that this is only possible for the basic ratings. Or at least I couldn’t find it anywhere in the instructions.

Thank you very much for your help.
