Is there any way to create an antisymmetric metric in Cadabra, like the spinor metric (charge conjugation matrix with spinor indices) in 11d? That is, I am looking for a way to create an antisymmetric object that can be contracted to raise and lower indices (as with eliminate_metric()), but it seems that objects with the Metric property in Cadabra must be symmetric.

Thanks in advance.
