Yes; Team Leads can change a buyer transaction coordinator, even if it’s not their listing.
To do so, follow the below steps:
Go to Listings/Transactions.
Click on the edit pencil next to the transaction.
Select “Edit Buyer Transaction Coordinator”.
Entering the desired Team member’s ID will keep the transaction under the Team account while putting that Team member’s name in the buyer broker field as “on behalf of" the Team.
