How to add companies to a group?

When inside the company's company information at the top are two buttons available. "+Add" and "New decision request". The "+Add" button allows you to add that company to an existing group or to a new one. 

Select the "+Add" button. 

-If you already have a group created, select the name of the group or groups where you want this company to be. 

-If the group has not been created, type the name you want the group to be named and hit "Enter."

Done, you have now added this company to a group.
