Unfortunately the DCM export script doesn’t support multiple exits at this time, but it is on our list to improve.
The best workaround right now is to add clickTag code to your Head HTML like this:
var clickTag1 = "http://example2.com";
var clickTag2 = "http://example3.com";
I would guess it could be compatible with the export script if you still use the clickTag as provided by the script and the
clickTag2 would be supplemental, but I haven’t tried that.
