User custom params/opttions in chproxy without adding to all requests through param_groups_config

[ingvar89]

Which feature your question relates to?
User defined params like FINAL or optimize_skip_merged_partitions

Question details
Chproxy removes all the query params from input requests (except the user's params and listed here) before proxying them to ClickHouse nodes. This prevents from unsafe overriding of various ClickHouse settings.

I need to use this parametres in my flow, but I can't pass it to all my requests, I need to allowed them to proceed when and where I want

Additional context/motivations
I'll be to add all params that user wants to dynamically adding in the user process
