Additional Line of Product Information on Store Pages

Hello, 

I created a store page that I use to have an overview of different practitioners in our collective and to give the user the option to filter by different kind of services each practitioners offers. 

On the store page, I would like to add an additional line of information, right under practitioner name. So far it only says the name, but for the user experience it would be great to give a bit more information. 

I can't find any option to create an additional line of information that is being showed on the store page. 

If needed: https://www.spiritofbreathcollective.net/collective password: Collective 

Any advice is highly appreciated.

Best,

Christian
