Is it possible to have multiple coordinates' markers for one note in Map view of Base?

What I’m trying to do

I’m trying to create a Base of favourite authors with a map view. On that map I want to show places related to the authors. It’s obviously that each author has connection with multiple places, so I wonder whether it’s possible to put multiple coordinates in one note and to have those markers shown on the map view of the Base?

Things I have tried

I've tried using 'list' type of property 'coordinates', but it didn't work.
