99.95% of the requests for CNAME at existing name can be summarized as follows
“If the RR type in question does non exit here please check this other name”. 

This is the same as many people used to believe about wild cards 
i.e. they fill in the blanks 

The “bad” news is that DNS is not designed that way and 
unless you are only using one vendor that supports features like this you are out of luck.
