New Column Type- for all contact details

It would be great if you could add a cloumn type that handled ALL contact details in one column rather than having to add separate columns for phone, email, address, name etc.
In some circumstances we have 2 contacts for one item (eg ‘product producer’ and ‘product importer’ ), so we have to have 6 columns (eg 2 x name, email & phone number). This is quite messy.
