Embedded Dashboards Limited by User Groups

My PHP-MySQL application limits user access to one of three Dashboard Collections corresponding to tiers 1, 2 & 3 user groups (e.g. Basic, Popular, and Premium).

Problem is Dashboards and corresponding Questions are hardwired for a specific Collection and must often be repeated with the only difference being level of data access (extended history, forecasts, additional granularity etc).

Can anyone suggest a way to pass the Collection value (1, 2, or 3) from the PHP-MySQL application to Metabase so as to use Linked Filters to accomplish the same thing without having to hardwire and repeat Dashboards and Questions?

The Discussion topic Dashboard Access to specific users looked promising but Sandboxing is really overkill for my purposes.

Hi @mesquest
Yes, with Locked parameters via Embedding, then you can code which values those filters have and the users will not be able to view those filters:
