The answer is yes, and while it is not totally straight forward, there are actually some classes supporting you. As Markus has pointed out, you first define your polynomial space. Then, you best check FE_Q or FE_DGQ for further implementation details. They both rely on FE_Poly, so if you can use that, your life already got much easier. It's also worth looking at FE_TensorPoly, since that uses a more convenient interface for converting from the original shape function basis to the one corresponding to the node functionals.
