Aggregate t-digest data

Elastic Stack Elasticsearch
1

I'd like to use ES to aggregate percentile data. Due to the size of the data, it is unfeasible to send all the raw data to ES. I'd like to generate t-digest on each agents remotely and then have the agents send the t-digest of data to ES. Will ES be able to aggregate the t-digests and allow queries to search for percentiles in this fashion?

Or is sending the raw data to ES the only way?

Thanks
