Assignation of components of a differential form (or multivector field) in sagemanifold

Dear all. I've crossed with the task of assigning components to a multivector field, and it's tedious! (specially higher ranks)

Question: Is there an efficient way of assigning components to tensors with symmetries?

Please add an example of what is tedious.

Yes, please provide some example. Note that when you assign components to a tensor with symmetries, it suffices to assign the minimal number of independent components, the other components are then set by (anti)symmetry.

@eric_g: Thank you! I didn't know that... I was assigning the components one by one! (there was the tedious part)
