From WeStrive, you can add an overview photo/video to both the program and each individual day. Keep in mind that clients won't expect you to add a program overview to every single day in your program (especially not a video for each day), but having a program cover image will make the app look a lot cleaner and will remove replace a basic icon as the cover photo with a beautiful image for your clients to look at.

From the program builder, just head to Details to add the profile photo, video, and description of the program.

To add the day overview, simply just click on the 3 dots in the program calendar and select Edit Overview. You can then add the day photo, video, and description.
