Recover Configure Tab after having been cleared

[mccap079]

macOS 10.13.6
Unity 2018.2.15f1

Perhaps I'm missing something but whenever the Unity editor is quit/restarted the Configure menu is empty forcing me to have to manually rebuild the bundle tree of hundreds of directories and subdirectories every time I want to add to/alter them through this browser tool.

Is there any way to recover the Configure tab to show all folders and assets from previous bundle builds or saved projects? Maybe some sort of .xml type of exported state, or some way to batch import all AssetBundle filepaths attached to each asset (visible at the very bottom of the asset's Inspector tab)?

Currently, if I drag an asset with a preexisting AssetBundle path (i.e., anim/anim1/anim1_in_1.png) into the Configure menu it incorrectly builds the tree structure in the Configure menu (hopefully that makes sense).

Update

In my Library folder I have AssetBundleBrowserBuild.dat and AssetBundleBrowserInspect.dat. Not seeing any "Configure" related things here.
