Setting the Time Tracking Default for my team

Hi There!
I’m managing a large retainer within Asana that involves around 21 different projects. While setting up our project within Asana and Harvest I realized that a game-changer would be the ability to preset each task (in this case individual project from the retainer) to their correlated Harvest tasks. That way my team members wouldn’t have to scroll through all of the projects we have when they click on the timer next to the task assigned to them.
As far as I can tell I have to personally customize the time clock settings every time I use it and that only affects me personally. Is there a way to manage this for my team to make it more organized?
