Hi, i´m searching for an option to use web forms, but only for existing Deals. 

I want to sent out a web form (Web forms, JotForm, Google Form...)  to collect further standardized informations from allready existing deals/customer in PD. 

Up to now i did not find any feature to assign that webform feedback, to existing deals.

Obviously web form can only be used to converte/create an new deal, out of the webform feedback of my customer. 

Any idea how i can update existing Deals with web form?
