 As a result, the `kbc sync pull` and `kbc sync push` commands will not synchronize these configurations.
 
+### Field-Level Ignore
+
+In addition to ignoring entire configurations or rows, you can ignore **individual fields** within a configuration.
+This is useful when you want to manage most of a configuration via the CLI but let a specific field be controlled
+exclusively in the Keboola UI (or vice versa).
+
+The syntax is:
+
+```
+{component_id}/{configuration_id}:{field_name}
+```
+
+Where `field_name` is either:
+
+- A **struct-level field** of the configuration — currently `isDisabled` is supported.
+- A **dot-notation content key** referring to a path inside the configuration's `config.json` content, e.g., `schedule.cronTab`.
+
+Example `.kbcignore` with field-level rules:
+
+```
+# Ignore the isDisabled flag — let the UI control whether this config is enabled
+ex-generic-v2/798412456:isDisabled
+
+# Ignore the cron schedule — let the UI control the schedule timing
+keboola.scheduler/801234567:schedule.cronTab
+```
+
+Field-level ignore is **bidirectional**:
+
+- **`kbc sync push`**: The remote value of the ignored field is kept. Any local change to that field is discarded before
+  the diff is computed, so the field is never pushed.
+- **`kbc sync pull`**: The local value of the ignored field is kept. Any remote change to that field is discarded before
+  the diff is computed, so the field is never pulled.
+
+In both cases the rest of the configuration is synchronized normally.

 **`kbc push` operation**
 
 The `kbc push` command will skip the excluded configurations and will not push them back to the project, even if they exist or have been modified in the local folder structure.
