Replacing several values in multidimensional array simultaneously

I have a multidimensional array, e.g.

A(:,:,1) = [1 2 3 ; 4  5  6];
A(:,:,2) = [7 8 9 ; 10 11 12];

I want to replace several of the values in this array with the same value simultaneously. Specifically I want to do this column-wise, the result should be e.g.

A(:,2,1) = [-1 ; -2];
A(:,3,2) = [-1 ; -2];

yielding

A(:,:,1) = [1 -1 3 ; 4  5  -1];
A(:,:,2) = [7 -2 9 ; 10 11 -2];

I attempted this by

B = [2 3]; C = [1 2];
A(:,B,C) = [-1 ; -2];

but it does not give the wanted result.

Any idea on how to do this without performing a for-loop?

A(:,:,1) = [1 2 3 ; 4  5  6];
A(:,:,2) = [7 8 9 ; 10 11 12];

s = size(A);
A(:, sub2ind(s(2:3),[2 3],[1 2])) = 0 % = [0 0; 0 0]

Thanks for your input. However, I have not been precise enough in my question. I need to replace a number of columns in the array with a column containing non-identical values (see the edited question), and not just 0. In that case your proposal does not work. Can you alter it correspondingly?

Just replace the RHS as I hint in my answer with "% = [0 0; 0 0]"

A(:, sub2ind(s(2:3),[2 3],[1 2])) = [[-1;-2], [-1;-2]]
