Hello, I have hundreds of files where the TITLE field is the name followed by the date in **MMM DD, YYYY** format. Is there a way to change the format to **YYYY-MM-DD** and move it to beginning (e.g. `interesting title - Jan 10, 2020` to `2020-01-10 - interesting title`)?

Any help will be appreciated!

Try an action of the type "format value" for TITLE  
Format string: `$replace($regexp(%title%,'(.*) - (\w+) (\d\d), (\d\d\d\d)',$4-$2-$3 - $1),Jan,01,Feb,02)`  
You would have to complete the list of months.
