One of the concept of GTD is the Tickler file, how do you guys implement it? I am from Toodledo and I have used the Start Date and Due Date from Toodledo.

However, it seems like Start Time in DOIT is something more than just a date, since it have Today/Tomorrow attached to it.

So what I want to achieve is that, let say every month I need to pay a bill, but I do not want it to come up in my "list" until 5 days prior to the due date. This was easy to accomplish in Toodledo, where I set
Start Date = 25th Jan 2014
Due Date = 30th Jan 2014
Repeat = Every Month

And then I just select to view "All Tasks", then sort by Due Date, with "Show Future Tasks" turned off.

Is there a way to accomplish something similar?
