+#### <a id="vreplication-shards-flag-start-stop"/>`--shards` flag for MoveTables/Reshard start and stop</a>
+
+The `start` and `stop` commands for MoveTables and Reshard workflows now support the `--shards` flag, allowing users to start or stop workflows on a specific subset of shards rather than all shards at once.
+
+**Example usage:**
+
+```bash
+# Start workflow on specific shards only
+vtctldclient MoveTables --target-keyspace customer --workflow commerce2customer start --shards="-80,80-"
+
+# Stop workflow on specific shards only
+vtctldclient Reshard --target-keyspace customer --workflow cust2cust stop --shards="80-"
+```
