That's exactly my point. I know what you want to say, I just don't think
these words say it. I think that your wording factors it out
completely. It's obviously not what you intend but it is what it says,
to me at least. "One or more bells may ring in the same position in each
and every row" means that, for example one bell, say the tenor may ring
in the ultimate position in "each and every row" of the block. Thus no
other bell may swap places with it because the tenor has got to be there
for "each and every row". Whatever bell starts there has got to stay
there for each and every row.
If you say that different bells may occupy the cover position in the row
from time to time during the block but do not participate in change
making whilst occupying that position, or words to that effect, then I
think you have what you want, and of course you can specify that several
positions may be "covered" if you so wish.
(When thinking of variable and multiple covers I think that the idea of
a bell covering a position so that no other bell can occupy it is
perhaps more helpful than the usual idea that the tenor is a cover over
all the other bells),
