Dynamic Contact form based on Conditions and Membership Area

Hey there boys and girls,

I have a very exciting project I want to set up as a SaaS. Hopefuly I can explain it well so here we go:

I want to setup a membership Area where registered users in wordpress have their own area/Dashboard.

In this dashboard they can create a new “Object” like a Parent.
In that Object they should be able to create another Object lets basically call it child.

What I need is a Form, where the user can Select both the Parent + one of their Childs.
Based on that a link should be created which points to a form that is “bound” or “pointing” to that 2 objects (Parent Child).

Why?
At the end of the month a user needs a report on a Parent basis. i.E he wants to know how many users have filled their data under all the contact forms of one “Parent”. So a report on Parent basis.

If you could give me some hints on how to maybe make this work or if it even can work with Contact Form 7 and some plugins for the membership area I’d really appreciate that!

Thank you so much,
Daniel
