### Is Einstein notation in sage available?

Dear all

I searched here. But I can not find an contented answer. There is a very usable notation in summations simplifying computations inclusive very $\Sigma$.

Is there a way in Sage that I can use this kind of notation? For more information, this notation is worked out in Cadabra.
