Not that I'm aware of. You could, however, perform a Copy Visible  
(this after you have placed your dots and realized your mistake), UNDO  
until all the dots are removed, duplicate the layer, Paste the copy  
buffer as a layer, change the layermode of the pasted layer to  
Difference, and Merge Down. You should end up with a layer of dots  
above the original map layer.
