If you're dealing with a small number of discrete values for the qualifier (the left column on your input), then I would recommend using the Conditional Split transformation. See this link for more information:

If your qualifier's distinct values is too large to allow this, you could use a script task but it may be overkill, particularly if you've never used a script in SSIS before. If you can post back some more information about what you're trying to do, I'll be glad to give you some more information.
