Does lego support alias mode?

CNAME all domains' _acme-challenge to an domain and add TXT record to the domain to verify. I cannot find such option in lib. And I also tryed to make a DNS provider struct which return a same domain but this cannot work.

Hello,

you can use: https://go-acme.github.io/lego/dns/#experimental-features

But there are no options to config the domain used to add dns recode. Should I make a modified provider to do this again?

Or it will follow the CNAME and find out which domain to use automaticly?
