Best way for multiple prefix rules

Is it possible to change prefixes for directory (without rewriting all rules)?

Styleguide says, that different modules can use different prefixes: toh-hero, admin-users. https://angular.io/styleguide#!#02-07

Module versions tslint: 3.13.0 codelyzer: 0.0.28

Now, I can write all prefixes in tslint.json in root directory.

"directive-selector-prefix": [true, "app", "toh", "admin"]
"component-selector-prefix": [true, "app", "toh", "admin"]

If I create app/heroes/tslint.ts, and write only rulesDirectory and prefixes rules, all other rules from ./tslint.ts will not work in app/heroes/ directory.

Example

./tslint.ts

{
  "rulesDirectory": [
    "node_modules/codelyzer"
  ],
  "rules": {
    ...
    "directive-selector-prefix": [true, "app"],
    "component-selector-prefix": [true, "app"],
    ...
  }
}

app/heroes/tslint.ts

{
  "rulesDirectory": [
    "../../node_modules/codelyzer"
  ],
  "rules": {
    "directive-selector-prefix": [true, "toh"],
    "component-selector-prefix": [true, "toh"],
  }
}

app/heroes/hero.component.ts

@Component({
  selector: 'toh-hero'
})
export class HeroComponent {}

the tslint extends feature works for this: I simply add a tslint.json file in the relevant folder like this

{
    "extends": "../../../tslint.json",
    "rules": {
        "directive-selector": [true, "attribute", "av", "camelCase"],
        "component-selector": [true, "element", "av", "kebab-case"],
        "pipe-naming": [true, "camelCase", "av"]
    }
}

The following format makes sense to be used:

"selector-prefixes": {
    "./": ["app", "baz"], // use “app” or “baz” by default
    "./heroes": ["toh"],  // use “toh” prefix for all D&C in “./heroes” except…:
    "./heroes/bar": ["bar"], // use “bar” for all D&C in “./heroes/bar”
    "./humans": ["hu"] // use “hu” for all directives & components in “./human”
 }

The keys are the directory names, relative to the project root, and the values are list of prefixes.

@ValeryVS any opinion?
