Create Sortable Column for new Client Type

Would be nice if we could have a Client Type field.

Something with the values: Customer, Company etc.

I have individual regular public customers, then also business to business invoices. In the future I will have online only customers so this type of field would be very beneficial.

If I could set the types myself, it would be even more amazing.

Would appreciate it if it could be looked at.

Maybe a feature vor v2.
