mp3 - number of downloads

Hi, is there a way in Perch to keep track of how many times an mp3 has been downloaded from a site. I have moved a client site over to Perch (they love it btw) from Textpattern, the file listing in Textpattern would show this value and they would like to add this to the new Perch system. Is there anything similar? in Assets or such like..?
