User created rules for Discovery and Coverage App

Discovery and Coverage app has rules defined at the below url.

/ui/apps/dynatrace.classic.settings/ui/settings/app:dynatrace.discovery.coverage:discovery.findings.default.rules.schema

As a customer I want to add some custom rules for our environment however these are almost immediately deleted. The app states:
Discovery findings default rules. This schema is not subject to manual changes, except for Muted setting. Any changes (except muting the rule) will be overwritten by the Discovery & Coverage application defaults.

My particular use case here is we have "Required" tags i.e App Name and Environment for each Host/Pg/Service etc.

The following DQL would provide a coverage of hosts that are not compliant with having the appropriate tags.

fetch dt.entity.host, from:-15m | fieldsAdd tags | fieldsAdd app = matchesPhrase(tags, "app:") | fieldsAdd host.id=id, compliant=(app == true)

As I cannot add a rule. I need another approach to signal that entities have been onboarded without the correct tagging metadata. I have this all in a notebook currently and am thinking of a metric event that alerts when the count is higher than zero, as a work around.
