Lifetime retention on specific stream when retention_enabled=true in compactor

Hi,
i have retention feature enabled in compactor.

compactor:
  retention_enabled: true

default retention is set to 50h

retention_period: 50h

in limits config section i have configuration like:

limits_config:
  retention_stream:
    - selector: '{namespace="default", app="app1"}'
      priority: 1
      period: 100h
    - selector: '{namespace="default", app="app2"}'
      priority: 1
      period: 200h

let’s say that i want to add app3 but for this stream i want to disable retention feature, so i can store these logs forever.

Is there any way to achieve this?

i imagine that i could set higher priority for streams that i want to rotate on specific time, then remove default retention_period key, thus default retention would be lifetime, then add retention_stream with lower priority with regex matching all streams, but maybe there is simpler way
