Frequently used customers/projects/tasks in time registration entries

Our organization has a lot of customers/projects/tasks, however, I only use a very limited set of those, but I use those often.
It would speed up my time registration if I could select my most often used customer/project/task easily, e.g. it’s possible to save those as a named template, and apply them with a click, or even just being able to create a bookmark in my browser that prefills those values would help a lot.
