Is it possible to convert several shapefiles at once and output separate attributes?

The reader in my workspace is an ESRI shapefile. I am clipping this to a buffer, changing coordinate system (SnakeGrid) and writing to a MicroStation .dgn. I am copying all the attributes from the .shp and writing as tags. Can I do this for several .shp's at once and it only carry the necessary attributes for each .shp? When I input '*.shp' to read all .shp in a folder, it outputs then individually but with the attributes of all the input shapefiles.
