Setting subform to add mode while main form is in edit mode

Is it possible to have the subform on a main form open in add mode
while the main form is in edit mode?
I have a main form that shows the first and last name of my drivers
while the subform is for entering a date and number of hours on duty
for that date. The subform is beginning to have a large number of
entries and I have to scroll down to the last entry to begin entering
data.

Thanks for your help
