"Reverse Transposing(?)"

[maroulator]

I have a data set that currently looks like the following:

LoanID  Mod_Date   Payoff_Date

422593  12/01/2005  07/23/2014

422593  04/09/2007   .

245234  07/09/2004  03/30/2008

245234  09/08/2006    .

353255  08/03/2006  09/23/2012

353255  03/04/2008    .

353255  05/21/2009    .

...and I would like to make it look like the one below:

LoanID  Mod_Date1  Mod_Date2  Mod_Date3  Payoff_Date

422593  12/01/2005   04/09/2007                        07/23/2014

245234  07/09/2004   09/08/2006                        03/30/2008

353255  08/03/2006   03/04/2008  05/21/2009    09/23/2012

Any ideas? Thanks in advance.
