time sheet drop down lists
 

I have set up a time sheet in which e6:e14 has a drop down list of times in
15 minute increments. This is the start time. I have g6:g14 with the same
setup only this would be end time. Is there a way that when I enter the
start time I will be able to enter the end time from the drop down list
without having to scroll down from the begining?
