How to tag leads from Zoho Landing Pages

Hi,

I would like to know if it is possible to add a tag to the contacts that sign up through a Zoho landing page.
In my case, Zoho Landing sends all leads to zoho campaigns, so it would be great to be able to put a tag on them to identify all users coming trough our landig page. 
Thank you
