I am trying to figure out if anyone has found a good workaround for trying to schedule workflows in Zoho Professional Edition.  I want to create a workflow that updates a CRM field based on some simple criteria for any lead that that has been created in the past couple of hours.

A standard workflow cannot be used in this situation because the field that the CRM is updating references a data set that is not immediately updated once the lead is edited or created.  We need to create a time lag in between when the lead is updated and when this workflow runs for it to be successful.

It's very easy to identify what leads this process needs to be run on.  I am struggling to find a way within zoho crm to take that list of leads that I can have created every 6 hours or so and have this process run on them.

Any advice, within zoho or using outside applications is appreciated.  Thanks!
