Is there a way to change the contents of the VCF file that is downloaded when someone clicks on the Vcard Link (that is added als a merge tag) in a mailing campaign?

Right now it's composed of data from my user profile (even my personal mobile phone) and company, so it's not usable. I want to customise it with the right contact data in this VCF files, for instance the phone of sales or helpdesk.
