How to Add Multiple Locations on Google Maps | Create a Map with Multiple Locations

Can I show multiple locations of my business on my Primary Google Page. So lets say I have a business A (primary), Business B and Business C where B & C are the new additional locations of my business A. Is there any way I can show B & C if a user/customer/viewer is looking at A on my Google Maps business listing page

Do you have any questions? I am happy to answer them:)
