Currently, tudat only allows to create (mutual) spherical harmonic accelerations that encompass all harmonic coefficients up to a certain degree and order. It would be a very useful functionality if accelerations could be created that only contain certain particular harmonic coefficients, like the "only C20" or "only C20 and C22", without necessarily including the sine terms or the C21 term in the second case.
