Use dots instead of dashes with naming conventions

I use the "Scan Files" feature regularly and I would love to have control over the format of the name given to the new file.

It is currently prefixed by the date in reverse (great), which I like, but I have ALWAYS delimeted using period whereas your default uses a mixture of hyphen, space and periods.

I would hope, however, that a user could choose this format, including datetime attributes and delimeters - eg. YY.MM.DD.HH.MM.<filename>.<filetype>

Would love to see this feature.
