If you have an Administrator that needs to be part of multiple groups, you can give them access to multiple groups. This needs to be done manually by the System Administrator. You can’t add multiple groups to an Administrator account via the batch options.
Select View Accounts.
Choose Administrator from the Account Type.
Find the Administrator you want to add to multiple groups. You can search or filter out the list to help find your user using the options at the top of the screen. Select the Administrator’s name or email address to access their account.
Choose the Account & Personal Details option. This will bring up the account details.
Find the Groups field. You can remove groups by selecting the X in front of a group. You can add a group using the drop-down.
Save the changes by selecting the Update personal details button.
