Hi,
Try multiplying the phasor you want to rotate with a gain block of gain 
such that 
and 
. This shifts the input phasor at the required angle without changing the magnitude. You could view the magnitude and phase of the output phasor using Complex to Magnitude-Angle block. Please refer the attached figure to see how these blocks are connected. Hope it works.
