Getting date attribute from file name

I am working through a creation of a rule for a set of powerpoint I have received. I receive powerpoint by email for meetings that I would like to save to a file name structure I like along with filed in a specific place. Generally to get the date I'd desire I'd do 'Content' -> 'Contains Match' -> 'Date Matching Token'. I know that due to the proprietary format Hazel is unable to read the contents of file to get the meeting date as I desire. The meeting date is included in the file but in a format that I do not like at all. In this instance the filename is 'Department_Meeting_6th Aug 2020'
Is there a way to get the date token to match in the file name to use later on when I process the file?
