Hide/Show a Dashboard using Bookmarks

Thanks for the response but unfortunatley row level security isn't want I'm looking for. The thing is that I'm not restricting the data based on the user's role, but instead restricting the dashboards that the user can view based on the specific contract that select.

The situation is that the PowerBI model holds all the same core data for many assets that are leased to various customers. Each lease, though, has a unique set of metrics that it calls out that need to be used to monitor and assess the lease transaction on an ongoing basis (the metrics are being calculated based on specific Measures and Calculated Columns). The only way to manage the varying requirements for each lease is to set up a unique dashboard for each lease with the associated metrics called out in the lease displayed in the dashbaord for that asset. So instead of confusing users with numerous tabs for many dashboards for every lease, instead I want to hide all the dashboards except only the one selected by the user from a front selection screen. I was hoping to be able to hide whole dashboards and then set up Bookmarks so that can then be asociated with a button that calls out the specific lease.
