How to score a lead in Zoho CRM when a form is field in Zoho Forms

Hello,

I have created some forms on Zoho Forms that are related to contents you can download on our website.

Depending of the forms, I would like to be able to score a lead in Zoho CRM. For example, if a lead fills the form A, I add 10 points. If he fills the form B, I add 20 points. 

Zoho Form is synchronized with Zoho CRM.

I don't see this option in Zoho Forms.

In Zoho CRM, If I want to create a scoring rule, I am not able to choose specific forms. The rule would apply to any forms which is not what I want to do (see picture attached).

How can I do it ?
I want to apply different score based on the forms filled in Zoho Forms.

Thank you for you help,
Camille
