Waiting for Multiple Files

Hello,

I will be receiving daily files that will use the following naming convention: YYYYMMDD_datatype.txt. The date will change on each file, but the datatype.txt will remain consistent
I would like to process the most recent file through Kettle and then move the files to a separate folder so that these files are not processed again in error.

Is there a way to do this in Kettle? I tried to use wait for file to bring in the files, but I don't believe I can use wildcards in that step.

Thanks in advance!
