Implementing OKR (Objective Key Result) Methodology

Implementing OKR (Objective Key Result) Methodology

I am searching for a way to implement OKR methodology in Zoho Projects. Recently asana has launched this feature in its latest update.

https://www.youtube.com/watch?v=Pdl30lWH2lY&list=PLNzc9PubwlIkev1VuIhSTzwc4aYPIncwz&index=5&t=0s on this link one can see how it works

I want to know how can I implement this into Zoho Projects

My idea:
1. Name the project group in Zoho project based on Objectives
2. Name the individual project (within the project group) as Key Results
3. Name project tasks as tasks of key results

But then the question arises that how can I have a dashboard for a project group where I can see the combined results of all the projects under that group

Please suggest some ideas based on this question.
