I like to have a reminder on many tasks in Zoho Recruit. I find the process cumbersome in that each task requires the following:

1.  click and select due date

2.  Click the reminder box

3.  Click on (Reminder) Start Date

4.  Click on (Reminder )Time

If one click on 'Reminder' auto completed the same date as the due date and the current time..  it would be big timesaver.. clicks add up.
