context aware configurations with dynamic property default values

Hi,

we are using context aware configurations together with the wcm.io editor(https://wcm.io/caconfig/index.html).

Is there any way to provide dynamic configuration property default values at runtime?

Or even better when talking about the wcm.io editor, to provide dynamic dropdown values?

All i could find where defining static values in the property annotation.

Do i have to implement a SPI? If yes, which one?

Thank you ver much!
