To manually create an origin:
Go to Apps.
At the bottom of the page, click "+"
At the bottom right of the page, click "Show All"
Scroll down to "Offline Media" and click "Otro".
Type the name of the origin, select the group you want to assign it to, and click "Save"
These types of origins are particularly useful to know, when a client is added manually, how did he contact your business
Note: Remember, that when you assign this Origin to a group, it will also be available to every other user belonging to groups of inferior hierarchy.
