Qcc3008 or csr8675 mono programming

Hi guys, i’m trying to get a mixdown mono output fron either the qcc3008 and the csr8675. But the only thing i get is a left channel only audio. I cannot figure out any way to get a mono output from that two boards. I tried Adk Config tool but i cannot find a way to go. Does anyone figure out how to do that? I get pretty easy result with csr86xx series config tool on older models of boards but these two are very hard to program in mono. Any idea? 🙏✨🤍
