Looks like dev-s are not interested in doing this feature request. I made a separate topic how to achieve this with a workaround. This example is with dynamic electircity price but you can make entity with a fix price and use that as well.
It’s actually not that complicated and using my example is doable by everybody.
Also reaching out to see if there are developers in our community interested in collaborating to bring this concept to life as a custom component for Home Assistant, accessible through HACS.
