Yes! If you'd like to simplify your onboarding process by adding a user to both your overall campaign AND a specific team simultaneously, use the team-specific join URL or join code.
You can find the team-specific join URL/code at Users > Teams > click the team name > JOIN CODE AND LINKS at the top of the page.
If users join your campaign on Impactive via those team-specific join URLs or via that join code, they will gain access to your overall campaign, and join that team specifically.
For example, if you're holding a specific event to onboard a certain team of users to Impactive - display a QR code with that team-specific join link, and the joining users will automatically be part of their particular team in Impactive. This helps keep your onboarding easy, and your users separated into distinct teams.
Of course, you can always manually move users between teams even if they've joined Impactive already. You can multi-select multiple users from any users table, then Manage > Add to Team; or add an individual user via their user profile page > Manage > Add to Team.
