Locking/turning off certain controls in properties panel/controlling bubble properties

It would be extremely helpful if we could lock and/or turn off certain controls in the properties panel when needed. Also, I would love to have more control over which bubble properties I want to surface - rather than all the properties associated with a component bubbling up together, it would be so helpful to be able to select the exact individual list items you want to bubble up.

We have a very complex dynamic template system that I’m building with a lot of nested components and variant properties, and while I need a lot of flexibility to allow for incremental changes, I want to limit what shows up in the properties panel as much as possible at each level so I can limit the decisions the end user has to make and accurately illustrate the possibilities and limitations that will be in our end product.
