Sleep Timer Intervall for Activities

Hi,

is there a way to set a sleep timer (for example 30, 60 or 90 minutes) for an entire activity?

Example:

Activity: FIRE TV

• TV on
• FireTV on
• Soundbar on

I want all devices in the activity FIRE TV to be shutdown after a specific sleep timer intervall, how can I do that with the Sofabaton X1.

Best regards
