Searching for sites when adding records to an activity

Submitted by kierandawkins on

I have created several site boundaries and included them in a single activity to collect records for them in a single place. If I submit a record to this activity myself I can search for the different sites by name on the record creation page. However, if other members of the group want to upload a record to the activity they are unable to search the sites by name, making entry much more difficult. Is there any way to make the sites I have created available to other members of my activity?
