Disable asset import and script recompile while adding/removing packages?

Is this supported, or possible through Editor scripting, at the moment? It's extremely tedious when you have more than one package (or Asset Store purchase) to add/remove from a project at once. It would be far, far, far more user friendly to be able to make modifications to the project in batch, and then trigger a single reimport/recompile once all changes have been made. I'm aware of EditorApplication.Un/lockReloadAssemblies(), but that only addresses part of the problem.
