Projects can be added to a project group when creating or editing a project.  Select the relevant group from the Project Group dropdown.

Note: the project group has to be created before accessing the new job so it is selectable from the Project Group dropdown in the add or edit project details.   Information to create a project group here.

Projects can also be added via editing the project.  On the create or edit project group page, select the project or projects that you want to add.  You can search for projects using the Search function.
