Link Letting Agents to Properties

Certain local Letting Agents look after particular properties. I would be useful to be able to link properties with agents and not all agents deal with all the properties.

1. It would also be useful if we could email all the linked agents in one go to let them know when a property was coming onto the market.
2. have check boxes so you know which ones you have instructed
3. once let send once email to informed all instructed agents that the property is now let
