How do I add a Sudo Handle to a Contact?

From a Message conversation:

• Tap the Sudo Handle at the top of the screen
• Tap the arrow on the right of the handle
• Tap Add to Existing Contact or Create New Contact

From the Call thread view:

• Tap the avatar icon on the left of the Sudo Handle
• Tap the arrow on the right of the handle under PARTICIPANTS
• Tap Add to Existing Contact or Create New Contact

From Contact Settings:

• Tap the menu in the top left corner
• Tap Contacts
• Tap the top of the screen to filter by MySudo Contacts
• Tap the existing Contact to add a Sudo Handle to (or tap the '+' button to create a new one)
• Tap the pencil icon in the top right corner to edit (if you do not see the pencil, you are trying to edit a Contact that was not created in MySudo)
• Tap Add Handle
• Tap Save
