Spanish TTS for Anki - Changing dialect possible?

Hi, why is the Spanish TTS in Anki in Mexican Spanish and not in Castillian Spanish? It would be nice if we could make that choice ourselves. I’m quite picky with having a correct accent. I’ll probably learn Mexican Spanish too, but now I want to focus on Castilian Spanish.

It would be helpful if you could make that happen. In the meantime, I’ll try out Arabic or Hebrew instead to see how it works since I already know some MSA Arabic and would like to become advanced in the language.
