How to add optional file paths to monitor under the packages field in release-please-config.json

[stecullum]

How do i add additional paths to trigger a release in a monorepo.
I have inherited a repo and the structure is not like any of the examples and its not feasible to restructure it just for release-please

For example updating a file under /src/app works as expected . A release is generated

"packages": { "/src/app1": { /* files that are modified under this path trigger a release */} }

However I need to find a way to add optional file paths to monitor?

eg...

{
  "include-component-in-tag": true,
  "include-v-in-tag": false,
  "tag-separator": "@",
  "separate-pull-requests": true,
  "packages": {
    "/src/app1": {
      "release-type": "simple",
      "package-name": "app1",     << seems to have no effect 
      "include-paths": [  <<<<<<<<<<< made up key
          "/src/app1",
          ".docker/app1-dockerfile"
      ]
    }
  },
  "$schema": "https://raw.githubusercontent.com/googleapis/release-please/main/schemas/config.json"
}
