Display message until acknowledged on Alexa

Hi,
Just wondering if there is a way to put a message on an Alexa screen that does not get removed until acknowledged.

Eg. The below says ‘Hi’ and displays it on the screen. However, it will automatically remove itself after a nominal time period. I would like it to ‘stick’ until I see it and acknowledge the message.

service: notify.alexa_media_kitchen
data:
  message: >-
    Hi
  data:
    type: announce

I don’t think there’s a way of doing that as it’s down to the Alexa device how long it displays the message for.
I guess you could take an alternative approach, and keep sending the message every x minutes until the time period is up.
