Export from Contacts module to Products module in Zoho CRM

Export from Contacts module to Products module in Zoho CRM

Good afternoon,

I would like to send a number of contact info from the Contacts module into the customized module (tickets to an event) in one operation.  I have selected several contacts in the Contact module (people who I have labelled as people I want to invite to an event) and I now would like to create a record in the customized module for each of them.  I can't find a way of doing this in ZOHO CRM. What I did was to export these contacts into a csv file and then import the data into the other module, using that csv file. But then, the link with the contact module is not created. I would think there is a way Zoho can do that automatically?
I hoep I explained clearly??!!
