Hide metrics on analysis page

I'm wondering if there's a way to hide metrics from the analysis page, and or reorder the metric list. as it stands we only have standard sql servers running on machines, so we dont have need for the Azure metrics, or the rds metrics, the cluster or VM ware metrics, but they're all there and all listed even through none of them have (or ever will have data) they done even have catagories to select from. This is amplified when adding custom metrics which add a catagory per each set and leads to confusion of which dataset is actually the correct one, since its right in the middle of the list 

Was hoping to be able to not show things that wont be needed as that list is rather cluttered.
