No, the TDC dials are not meant to be operated manually. Only the "Own ship" dial is clickable and it will make you cnage course, but it is not the best way to do that. Unfortunately, you must update or change things by repeating the step of "manual input" with the tool of the upper left corner of your screen each time you want to correct something.
Hope in the 1.2 we are allowed to manually tweak the dials like we did in SH3.:hmm:
