Ability to hide or show a workspace parking lot in a pivot table report.

Our team uses pivot table reports shared through the webpage URL capability to provide senior leadership with a view of what's coming. Parking lot items are not ready for that level of review, but we are unable to 'hide' or even label the parking lot column. You can see an example at this link: https://bloomberglaw.aha.io/shared/a48118bc84165d57bfbd4729d8dab455
Note that the parking lot column appears as the unlabeled column at the end. Thanks!
