Choosing which phone number to dial from / send message (business vs personal)

Hey all,

I am trying to setup simple ways for our team to be able to text / call clients using their Macbook.

They supply their Macbook, but we supply the iphone.

Because it’s their Macbook, the icloud account is linked to their personal number.

What do you think is the simplest way to be able to send messages / make calls and choose the number it comes from (from their Macbook)? Is it setting up another ‘user’ and then using quickswitch to toggle between them (when in work mode vs personal mode?)
