I recommend using the Rename Feature.
The example below will not suit your needs, but should help you create a preset that does what you want.
I often rename photos starting with the Date Taken (without the time). Here is one of the presets I have created: .
In place of TEXT, I would typically enter my client's name.
This preset will add the date Taken in YYYY-MM-DD format at the beginning of the filename because then the files will sort the same when sorted by filename or by Date Taken.
