How to add pullback to fiducial marks on PCB?

Hey All, Wondering how you go about adding a fiducial with pull back? I can add a fiducial, but I can't seem to control the pullback. I searched but didnt come up with anything useful. Can I edit the solder mask layer? I'm making a very dense LED array and Want to add two fiducials to help in keep accuracy high during assembly. Thanks! Andy

I think you need to turn on the soldermask layer (the cog in the layers list), and put (copy) the fiducial to it. The soldermask layer is interpreted as a negative...

Edit: I tried to make a non plated circle under a smaller plated one, but the gerber viewer doesnt represent the non plated circle... Maybe that's just graphical?

@terjekbela Thanks! I tried to add to the solder mask layer, but I'm unable to assign the shapes to that layer. It only lets me assign to Top, Bottom, and Document... but not solder mask... I'll keep trying. maybe need to restart the EDA to pick up the layer change? Thanks!

@aseredy yes, I've seen that problem, too... restart will help

Thanks! Restart did help, but I can only add rectangles and solid regions, not circles. I added a square onto the solder mask layer, but it treats it as both the etch layer and mask layer. So I end up just making a non-masked copper square. hmmm

@terjekbela Wait, I think it's working. Loading it in a gerber viewer seems to show the copper circle and solder mask as two separate objects. The Picture Viewer in EasyEDA seems to confuse the two. Thanks for the Help. I'll order some Test PCBs to confirm.
