Portal - restricting certain links on a portal to specific users
I'm brand new (less than 1 week) to Smartsheet.
I am creating a portal for a multi-user type team. We are the architect for a multi-location client. We use Smartsheet with the client/ owner, contractor and engineers as well as our internal project team. I want to have certain links to sheets be available to everyone and some to be available only to our internal team, but I want it all accessible from the one portal so there isn't a duplication of data. If I set sharing restrictions with each sheet, will that do the trick? I don't want the owner to see our internal task list or proposal checklists, but I want it all in one place. I would create a Architecture Firm Name Internal Team Section at the bottom of the portal.
Thank you for any guidance you could give.
