Regarding the problem that you want to read the costs per function: have you considered using resources tags? This could help a bit when evaluating your costs (though not directly on the bill). https://aws.amazon.com/answers/account-management/aws-taggin...
I've read about them yeah. A friend also showed me recently the power of stuffing the advanced billing CSVs into Redshift and querying them with Tableau or something.
Personally, I think it's all fucking ridiculous the amount of effort you have to spend into reading your own bill.
