Currently entries can only be linked to an account record and assigned to one user.
Being able to link to a specific Sales Order / Purchase Order (or delivery note) would enhance this feature as would being able to assign it to several people, or a 'Team'.
For example we make a diary entry to 'Goods In Team or several people' attached to 'PO' to advise when the delivery is scheduled, so they can see what to expect in and a daily schedule of movements.
When Customers call chasing an order, rather than an entry against the customer an additional link to a specific order, would narrow down, and improve in making a response.
