When configuring Form Rules, now you have the option to define a Value for those fields that you can consider dependent based on a set of Conditions.
Thanks to this amazing functionality you can specify a new Owner for a quote once it reaches a certain Stage. For example, when a Quote reaches the "Ready for Approval" Stage, we want to assign it to 'Garry Manning' the manager in charge to approve Quotes. This way as soon as anyone on the sales team updates a Quote to the status 'Ready for Approval', it will automatically assign it to Garry for his review.
Since Form Rules can be based on Roles, you can create really powerful combinations to set these dependencies.
