Select multiple entities at once inside a package to be deleted

Since we are unable to delete packages entirely, the only option when you need a package removed is to delete all of its contents. This however can be a huge amount of time spent repetitively clicking since there is currently no way to select multiple entities at once when editing a package. Below is a short demonstration of this issue in action, you can imagine how tedious it can get for a package with hundreds of voxel meshes etc inside!
The ideal scenario would be the ability to select multiple of these at once using CTRL+Left Click, as one would do in the “Entities” window.

(Please forgive my naming conventions on the voxel meshes!)
