 ### Instance Management (Deployment Role)
 - Create instances from templates at a specific site.
 - Assign instances to areas.
- Bind data connections — **per-attribute binding** where each attribute with a data source reference individually selects its data connection from the site's available connections. **Bulk assignment** supported: select multiple attributes and assign a data connection to all of them at once.
+- Bind data connections — **per-attribute binding** where each attribute with a data source reference individually selects its data connection from the site's available connections. **Bulk assignment** supported: select multiple attributes and assign a data connection to all of them at once. Each row also exposes:
+  - **Override** — optional per-attribute OPC UA node id (or other protocol address). When set, replaces the template's `DataSourceReference` at flattening time; when blank, the template default is used. The greyed placeholder shows the template default for context.
+  - **Browse…** — opens the OPC UA Tag Browser dialog, populated live from the site's OPC UA server via `BrowseOpcUaNodeCommand`. Visible only when the row's connection uses the OPC UA protocol; disabled until a connection is picked on that row. The dialog lazy-loads the address space, supports manual node-id entry as a fallback, and remains usable when the site or its OPC UA session is offline (the manual-paste field stays active even on error).
 - Set instance-level attribute overrides (non-locked attributes only).
 - Filter/search instances by site, area, template, or status.
 - **Disable** instances — stops data collection, script triggers, and alarm evaluation at the site while retaining the deployed configuration.
