arcgis desktop - Using wildcard to Append multiple feature classes in ModelBuilder?

I have a folder of shapefiles and each one starts with a code. There are multiple shapefiles that start with each code, and I would like to create a model in ModelBuilder that will select the shapefiles that have the same code, and append them into the appropriate existing geodatabase feature class.

Is there a way to use a wildcard in the Append tool, like to specify that any and all files in a certain folder starting with 'XPGC*' get appended into the 'Pipe_Grade_Change' feature class? Or is there a way to use an iterator to accomplish this?

Answer

I would use Iterate Feature Classes and Collect Values as in the graphics below.
