Feature Request

Is your feature request related to a problem? Please describe

When you have a complex device with dozens of Associated Graph Templates added to it, it becomes cumbersome to add more.

Describe the solution you'd like

Make it possible to hide the contents of Associated Graph Templates and Associated Data Queries when editing a Device, but keep the "Add" dropdowns. Additionally, it would beneficial if the Select Menu's were searchable as with select2.
