Get locations from database and output override

Hello,

I am interested in purchasing My Maps Location. I have some pre-sales questions:

1. Is it possible (via API or something) to retrieve the locations from database? We may need to get locations from the extensions which My Maps Location doesn't have integrations, eg Membership Pro, Easy Profile, Akeeba Subscription...
2. Is it possible and easy to customize the output of the list of locations on the right side of the map, without modifying the code of the extension (like Joomla template override) ? We will need to add some custom call-to-action buttons, eg "Call now", "Buy now",...

I look forward to your reply.

Kind regards,
Hung Tran
