Hi @4090-1,
It’s possible only if you connect each Place ID manually (by hand) before using it on the pages. It will not work through a template shortcode with dynamic place_id parameter.
And the second problem in Google API. To use the plugin you must enable a Google billing, it’s needed for API key and Google gives only $200 per month to use the API, it should be enough to add up to 10 businesses, but if you need more, it will cost expensive, sorry, I can’t tell how many, but on Google you can find awesome manual with all this pricing, we just didn’t deal with it.
Thanks!
