Deleting Large Amounts of Items

I'm running a campaign for Lost Mines, and I recently added in one of the Tales of Yawning Portal to take a look at it. I was browsing the handouts but decided I wasn't going to use it yet so I right clicked the folder containing all the items to delete them from there, and it deleted the folder but released everything inside into my page settings. How do I delete these? There are over a hundred. I just want it removed from my page settings.

I'm afraid individual deletion is currently the only option.

Im not sure its possible but if its just the Tales part you are looking to clear out and that was the last of your entries you may be able to roll back instead and remove it that way. This may be Pro level only.

Rollback is a Pro subscriber perk.  Upgrading to Pro would give you that option, if it would work for you.
