How to loop joining all files in a folder to a plate map?

KNIME novice here, so forgive my lack of knowledge:

I have a high content screen performed in 384 well plates. Each plate has a corresponding file containing the results of the image analysis. I have the following workflow which I need to apply to 120 plates:

Excel Reader > Join Layout > Normalizing Plates > Excel Writer

How can I loop this workflow to read each file, do the joining + normalizing, and then name and write the output?
