Reset a Rotation Matrix (or a Quaternion) Axis.

Hi, I have a problem. I have a rotation matrix with some rotation. I want to reset, for example, absolute Roll, but without modifying the pitch and the yaw. I dont know how to do it... I've completely lost a week trying to do this.
The maxium thing i've done is to get the Euler angles from the matrix, reset one axis and then create a new Rotation Matrix.
I dont like this way because in some positions, the Euler angles are not fiable.
