Account Integration and Multiple G Suite Accounts

I run a project Management agency. Each one of my clients is a different project for me to manage and i need to be able to access their G suite connections separately within my account because i need to manage my timelines as a whole company not just strictly based on one project.

But as it stands The only option I have is to create a whole new workspace and pay for another subscription just so i can connect their account and then its in a separate workspace.
I need them all to be in the same workspace in a respective portfolio so i can manage them properly with oversight. Is this not possible in 2025? It doesn’t make since for me to create an entire workspace for a new client just for a 2-3 month project just to close it right after and then I have no way to monitor all my projects as a whole because they are in separate workspaces. Does anyone have any tips to get around this?

To addd on-
That means that I would also have to pay for each of the seats of my team for each individual client. which would be quite expensive.
