One can append the L1Nano output to the `cmsDriver` command via the `NANO:@Phase2L1DPGwithGen` autoNANO handle, e.g.:
```bash
cmsDriver.py -s L1,L1TrackTrigger,L1P2GT,NANO:@Phase2L1DPGwithGen
cmsDriver.py -s L1TrackTrigger,L1,L1P2GT,NANO:@Phase2L1DPGwithGen
```

Check `PhysicsTools/NanoAOD/python/autoNANO.py` for the way this command is defined.

Note that the step key `Phase2L1DPG` does not include the generator and reco-level objects used for MenuTools studies in the nano!
It is mostly created for workflow tests.
