I have a doubt with the Logbook section of an object. I need to know if is there any way to track de changes of the Contact Assignment, or if there's any version that allows this.

For example, I create a Client named 'Lenovo Notebook' and I have 2 persons 'John' and 'Frank', when I created the Client, I put these 2 persons to the Client, 'John' is Primary Contact and 'Frank' is just another one in the list. As the time passes, this Client has changed its Primary Contact, now 'Frank' is the Primary Contact. But when I see the Logbook of the Client, this change is not recorded, the only record of Contact Assignment that appears is when I created the Client and is the assignment to 'John' and 'Frank', but the Primary Contact change doesn't appears.

Just to be clear, I'm using the 1.14 Open Source version.
