Insert a blank row based on the value in a certain column

I am trying to find a macro or add-in that will insert a new row when it finds a change in value in a particular column.  In example below, I want to be able to select column A (Team) and have Excel insert a new row when it finds a new value. In this case I'd get a new row under Team and then under 0123.


TEAM      SCHOOL      STYLE    EMBELLISH       GARMENT COLOR      
0123      PURDUE      BAC           WDMK         BLKOGD                     
0123      PURDUE      BAC      WDMK              BLKOGD                     
0143      BAYLOR      BAC      WDMK        HNTGLD                     
0150      GEORGIA      BAC           WDMK          BLKRED
