Choose sites for item/ default assigned sites

Hello, we are working with Omeka S, we plan to have a main archive, and two additional sites that represent two cemeteries. When we add items to Omeka, it automatically selects all sites and we have to exclude the ones we do not want. Is there a way to add items and the items only be added to one default site? or create a resource template that has a specific default site?

You can take a site out of the set that’s chosen by default by deactivating the setting “Auto-assign new items” in that site’s Settings section.
