Light icon colour temperature in dashboard

Hi,
Is there a way to set default color_temp for lights that don’t have that value?

Example:
I have a “dumb” LED strip that is cool white 6500k, controlled by shelly RGBW2 with Tasmota on it.
The controller is set to just pass the light state no color_temp or colour in general. When I add the light to a dashboard and turn it on, it is by default showed as warm white, can I set my own value for this somewhere if the light doesn’t provide one?
