With the Store Locator app, there isn't a way as it creates a shop specific proxy page.
However, this was a common question so we built a web app that can be used on any platform, any website and can be embedded multiple times. It's called Mapply. If you want to switch to that, you can Bulk Export Stores in Store Locator and import the store locations into Mapply.
Store Locator is the same; it's just not platform-specific.
