Putting an action layer over a layer with a clickTag element

Hello,

I am doing some research on creating clcikTags. I read a few places that the clcikTag should be on the top layer.

That has been fine, but now I want to loop it and I usually put my actions in the top layer. Will this cause a problem? Am I better off just putting my loop  action on the last key frame of the clcikTag layer?

thanks!
