We use Mail Merge from Zoho CRM pretty often for our deals. We currently have a field called "Date of Payment" in our Deals Module, and we pull that date into our Maile Merge Templates without issues. Now, in addition to displaying the "Date of Payment" value, we need to display a date that is 30 days after the "Date of Payment" (Date of Payment +30). Is there any way I can have the Merge Template setup to add the Date of Payment + 30 value?
