Yep, you’ll need to create a range for each character and add this expression to each one:
for X rotation:
C = thisComp.activeCamera;
V = C.toWorldVec([0,0,1]);
P = toWorld(anchorPoint);
lookAt(P, P + V)[0];
for Y rotation:
C = thisComp.activeCamera;
V = C.toWorldVec([0,0,1]);
P = toWorld(anchorPoint);
lookAt(P, P + V)[1];
for Z rotation:
C = thisComp.activeCamera;
V = C.toWorldVec([0,0,1]);
P = toWorld(anchorPoint);
lookAt(P, P + V)[2];
