Add Additional buttons at top of screen

Since our 'events' are typically on-going over the course of a year we enter volunteer  hours each month for the preceding month.  We would like to see a way to enter a range of dates when entering  hours and also to have the 'main dashboard' etc. buttons included at the top of the screen.  At this time after I enter hours I have to scroll down through numerous volunteers to get to the buttons at the bottom to move to the next area.  Some of our opportunities use 20 or more volunteers, which means we could have a monthly enter for each of those volunteers.
