Dynamically generating Date Field

Hello All,

I have a requirement to have a field in WebI report which has Month-Year from a particular month say Jan-2013 as shown below.

Jan-2013

Feb-2013

Mar-2013

Apr-2015

Is there a way to dynamically generate this? And the end month-year should change dynamically Per the current month.

Responses are appreciated

Thanks!
