It would be great to be able to select a Definition Query without having to select a layer (or several) first. In my map I created Definition Queries for several layers giving them the same name. So when I select those layers I can already set the Definition Queries for all layers at once. However, it would be easier if I didn't have to select the layers, because then I have to remember which layers have a specific Definition Query and which don't. I just want to select a Definition Query and activate it for all layers it can be applied to.
