Where is the scheduling manager for Analysis Workspace shares?

In Analysis Workspace, I've been using the "Share > Send File on Schedule" feature to setup weekly and monthly PDF sends to my stakeholders that don't have access to our Adobe Analytics account. However, I can't figure out how to cancel, change or even see a list of any of the scheduled shares that I've created in Workspace.

Normally to see the list of regular Analytics reports that I've scheduled, I go from the main Analytics navigation to "Components - Scheduled Reports" , but this list doesn't include my Workspace PDF scheduled shares.

Any guidance with this issue is appreciated. Thanks!
