Controls Default setting in V3.7

Using Sitefinity V3.7 

When I load a control such as an "image gallery" or a "Document Download" control, the admin page defaults to "ALL LIBRARIES"
This is not desirable as Sitefinity bogs down trying to initialize all the images in all the libraries or all documents in all doc libraries.
I'd like to create a small image library or a small document library and have the controls default to the small libraries to save an enormous amount of time. The author needs to select their own library anyway, so why not default it to a small library?

Does anyone know where this default setting may be located?
