Alexa validate input

I have a question about Alexa integration.

I saw that input select is not supported. For this I did the workaround with the template switch.

This works well so far, because it is a selection of programs. However, depending on the selection for another input_select (temperature), not all combinations are possible. This means that depending on the program selection, only certain temperatures can be selected.

Anyone have an idea how to implement this? It would also be enough for me if you select a temperature and I start a scene and Alexa tells me that this selection is invalid. Is something like this possible?
