It would be nice to have a new control available to the Duration field type.

for the end users on the mobile application they are presented with a drop down of values that are selectable.

if the values are not in the drop down the user must manually type in the value.

if the control could allow the control of intervals 15min, 30min, 1 hour etc.

users will often select 1 day for a 8 hour work day and in actuality is 24 hours.

this would greatly reduce errors in data entry
