Fingerprint b64 not URL-friendly on pipelines

Hello!

In our ingestion pipeline, we use a field fingerprint as an ID. This ID is used in API paths for searches, such as /host/{id}.

We are having problems with B64 due to Elastic transforming the fingerprint to B64 before saving it.

Is there any possibility of changing this to BASE64-URL-friendly or HEX?

Thank you.
