We do have rigid type of Element similar to RBE2.

We need a command snippet where we define loads and bc.

To convert the beam 188, we need to define them so say, et, 1000,mpc184. Then select the beams with esel, s, ename,, 188. Finally use the emodif command, emodif, all, type, 1000. This is on top of my head so check the command in our help manual.
