marking of centroid in drawings

hi folks

i hope some of you brighter sparks out there may be able to help, i have ben asked by one of our engineers to create a calculation drawing for one of our many cast parts

this in itself is not a problem, the problem i have is that we need to show the centroid of each section view, in the part this is shown when you use section props, i need a nice easy way of showing this in the drawing, even though it does say were the centroid is in section props and i have put all this info in the drawing the engineer requires it in the drawing as well, it can be worked out by calculator (but i think they have forgot how to use one), all i get at the moment is autocad can do it so why not solidworks.

i hope some one has a fix for this as it is driving me nuts

thanks in advance
