Good day fellow AT'ers

I can copy paste multiple company names into an empty field of 'companies' in the interactions table.

The result is that AT will add for every company a new interaction. For example, if I paste 3 companies, AT will add 3 new records of new interactions.

This is great, but what if I want to add the 3 companies automatically into the field? I can do it manually, but if there are too much companies this is not feasable.
