To assign specific volunteers to a role within an opportunity:
If you are in more than one organization, make sure you are in the right one.
From the navigation menu, click Opportunities.
Select an opportunity, or use the search box to find and select an opportunity.
In the opportunity menu, click Schedule, and then click Roles.
Select a role from the list of roles.
Click Take Action, and then click Edit Volunteers.
Select the volunteer(s) you want to add to the role.
Click Save.
Tip: To link a role to a qualification, click Take Action, and then click Create New or Add from Existing within the Qualification actions. Linking a role to a qualification makes the qualification a prerequisite for the role when volunteers sign up for the opportunity.
To manage scheduling gaps across multiple shifts and opportunities from one place, assign volunteers to roles from the Central Schedule page.
