Track resources via current tags
It would be nice to be able to query the Consumption API against the tags currently applied to resources and have the option to identify past usage before those tags were applied.
This should only be an option - there are certainly cases where you might prefer to have the tags as of the date of usage.
This is definitely needed!
Let us know if there are specific cases where you’d like to be able to look at costs by the tags when they were applied vs. the current state of tags viewed retroactively. Understanding your needs will help ensure we cover the specifics for you.

Looking for retroactive tagging.
Use case is inconsistent tagging on resources making it difficult to generate accurate cost reports. We can add a new consistent tag to all Cosmos DBs today and start seeing their cost/projected cost going forward, but would like to easily be able to generate a report breaking down cost per DB over the last year.

I agree. It would be good to maybe look at adding this feature. I can see many times, specially when people are just starting with tagging resources, they would like to see how much that tag cost them previously.
