Filtering(searching) contact info by using subform info

Hello there,

Is there any ways to filter(search) Contact info by using subform info?

I am trying to manage my customers info in ZOHO CRM.
My customers are mainly families so I set up a family member is a representative as default form and other members are additional info as subform(relationship, name and birthday).

What I want to achieve here is to search main info's address by using subform info(such as son's birthday) so I can use it for campaign or sending birthday DM's

Thank you,
