I have a follow-up question:

What about when I have multiple timesteps...

```
import xarray as xr
import glob

file_list = glob.glob(target_dir + '*.grib2')

ds = xr.open_mfdataset(file_list, engine='cfgrib', combine=""nested"", concat_dim=""generalVerticalLayer"")
```

It does load the data, but it does not get the dimensions right. Note that I attached a new dataset, which in the end should have the dimensions lon, lat, vertical and time.

Thanks for your help!
