Sales by Seller

It would be nice to have the option of having different vendors Do not confuse vendors with Aronium users For example it happens that in a hairdressing salon,A client can be attended by several salon staff Example The XXX client The hairdresser Juan Perez makes the haircut The Auxiliary Maria performs the nail repair,And the auxiliary Aida gives you massage therapy 

And the option of users of the aronium system could not be used, since it implies leaving to register with each user and then you cannot unify all the services received for a single sales ticket

It would be great to have the option at the time of making a sale to establish who was the seller who attended it and then have sales reports of each seller Another case that occurs is the business for departments, in the same store you can buy a cell phone and attended by a mobile specialist seller and at the same time buy a computer and is attended by a technical seller and makes a single payment, I want to know If the idea is clear, I previously made a similar proposal but the answer was not valid,

Thank you
