Hello, and thanks for your feedback! This functionality exists today in our InsightGO product, all you need to do is click on the View Appointments button in the upper right portion of the Scheduler, then select the Therapist tab, choose the therapist, and you'll be able to see all available appointment blocks (including lunches, meeting times, etc). From here, you can select each item you'd like to delete with the check box on the left side of the list grid and click on Delete Selected in the bottom right hand corner.
We recognize that there is opportunity for enhancement of this workflow and are considering changes in future iterations for InsightGO. If you have any further questions feel free to contact Insight Support via Support Hub and log a case at supporthub.webpt.com or call (503) 525-0275 (option 2) and notify them of any issues.
