I want to require to fields to be filled out before a quote is able to be sent. What is the best way to go about this? It looks like validation rules only apply to that object directly. When I send a quote, the status is automatically switched to "presented". But I'm wondering if it's best to just give you an error as soon as you click "New Quote". Anyone have any ideas for this? And since it's automatically switched to the stage "Quote Sent" when you send a quote, I don't want to make a dependency for that stage.
