Recently I noticed that the setting "queryparameterCleanups" is only available via API - there is no such option in the UI and AFAIK there is no Settings v2 schema for it either - at least none that can be applied with scope "APPLICATION" (e.g. the schema "builtin:rum.web.resource-cleanup-rules" only supports the environment scope so far).

From UI I am using placeholders to clean up parameters sometimes:
