How to add time stamp to a file (.jpg) with Mapkey?

Dear Members,

I have a question about adding a time stamp to a mapkey. We use a mapkey (seen below) to quickly make .jpg-files in an specific folder. We would like to make multiple files of the same part number, but this gives a failure because it cannot give the new file the same name as the previous one. We would like to add a time stamp (DD-MM-YYYY & Time) behind the file like :    partnumer_11-02-2015_12:05.
