It is possible:

* store the current file name in a variable (you can configure this in the for each loop)

* inspect the file name with a script task. According to the value found, set another variable (for example: if _Product_ was found, store Product in @typeFile variable)

* connect the script task to 12 data flow tasks (assuming each file has a different layout). In the precedence constraint, use an expression. For example: @typeFile == "Product"

The downside is that you are processing file per file.

While 12 for each loops may seem ugly, it will probably be much faster.
