Format %datefile% and %timefile% variables?

Good day,

I can’t find any posts on this topic, but I was sure I had posted something in the past about this, when 10.x wasn’t released yet.

Can you format the output of the %datefile% and %timefile% variables?

I’d like to be able to format %datefile% to be mm-dd-yyyy or mm_dd_yyyy and change timefile as I see acceptable for my customers.

Thanks.
