Use combvec for pairs of values

Hello,
I have a matrix (20 x 2) .
I would like to create 4 possible combinations of each pair of values present on each row of this matrix into a new matrix with 8 columns.
Basically, I would like to use combvec but instead of using scalars, I would be using pairs of values.
Any ideas?

If there's only two columns, what's wrong with just doing
A = randi(9,20,2)
B = A(:,[1 1 1 2 2 1 2 2])
