convert 2D -> 3D molecules in a studio table

Hi,
I have a large bunch of 2D molecules in a studio table just inserted from an sdf file. I would like to make them 3D and optimize their structures in one go, without having to run Discover one by one molecule and reinserting the resulting 3D structure in the corresponding cell of the studio table.
How can I do that?
Thanks,
Gonzalo
