Similar comment from myself… viewing contacts by Companies. All related Contacts are pulled in automatically by enabling
‘Automatically create and associate companies with contacts.’ - great it works well, however, if you want to add a new contact to an existing company via that screen, you have to complete all the separate fields to the new contact about the existing company!
It would be fabulous for HubSpot to enhance the functionality/add to the development that if there is an existing company in the portal, when you want to add a new contact to that existing company, that the details are pre-populated to the new contact fields, adding an even better user experience, saving so much time.
Taking it one step even further, if the company had multiple locations, adding a drop-down on the fields to choose from!
Come on HubSpot, I know you want to 
Thank you - Alison
