[Plugin: Google Maps via Store Locator Plus] Use same location data across networked sites?

I have created a WordPress network that comprises about a dozen sites, and have installed the Store Locator Plus plugin at the network level. The list of locations to be used on each of the dozen-or-so sites is identical. Is there some way to enter the data once and have it be shared across all sites?
