Support Smart Link navigation to a specific Genesis page

Summary

Users cannot share a link to their current view when working on a Genesis page. This breaks a common collaboration workflow — e.g. a Finance user filtering a report to a specific scenario or entity and sending a colleague a link straight to that same view — which already works today on classic dashboards.

The technical root cause: a Smart Link can currently only open the Genesis container dashboard, not a specific page inside it. Which page displays is controlled by the internal cph_Nav_Home_(Main) parameter, which OneStream Support confirmed cannot currently be set or read from a Business Rule or Smart Link.

Requested enhancement

1. A supported way to target a specific Genesis page when building a Smart Link
2. A supported way to read the current Genesis page's identity from a Business Rule bound to that page (equivalent to args.PrimaryDashboard.Name for classic dashboards), so one reusable rule can link back to whichever page the user is on, without hardcoding.

Impact

Without this, teams migrating to Genesis lose Smart Link "share my view" functionality that worked on classic dashboards. The only current workaround — exposing each Genesis page as its own standalone dashboard/profile — undoes the point of consolidating pages under Genesis.
