I have used coded steps in a large number of tests.  

But the common theme that I noticed is that the coded step is using a dynamic object like DateTime.Today.ToShortDateString().  

When I initially record a step, the date would be in a string.  The step would playback as the same string.  But with dynamic objects like DateTime.Today gives me the ability to test the system further.  

I could think of one option that relies on SetExtractedVariable(), but that still requires me to write some code. 

Today, days from today, months from today, and years from today.
Probably other users may like to see similar time options as well.  

While it is easy enough to make a coded step, it would extremely helpful to have a quick setup for using dates instead of converting a step to a coded one.  

Maybe something that would be similar to how test steps have the ability to be bound against a specific data source.
