Can I use the file mask to import a CSV that was produced yesterday?  The data source I'm using (Toast POS) exports CSV files at 4am for the day prior in a folder structure like this:

RestaurantID / yyyyDDmm / TimeEntries.csv

So if I run this task at 4:30am on June 1, 2023, it would need to open the folder for May 31, 2023.  

Is there any way to use a date function in the file mask? Or any other way to get yesterday's date in there?
