Trev,
The table on my BCA has a plain bore [set slightly below the table surface]; and a Pin [with a female centre, and a knurled grip] that's very slightly tapered … used for aligning the table under the cutter.
I have made a set of "Top Hat" inserts with various diameter pins, that are a sliding fit in the bore, for doing the sort of work that you describe … These are easily removed with a small button-magnet.
Roger's solution seems to bring the MT2 taper to the same conclusion.
