Variable Target alignment

MaxPierce

I am programming an IRB 1410 Arm to weld.

I am programming the paths and there are some parts where the welding tool could physically reach the target but my target orientations are too strict. 
I am wondering if there is a way to set a range of allowable orientations for targets.
for the targets i only need a the Z axis to be aligned and 130 degrees of rotation in the XY plane is clear for the welding tool
