I want to add manually triggered workflow_dispatch to GitHub actions as follows:

on:
  workflow_dispatch:
    inputs:
      rollbackSteps:
        description: "Input rollback steps"
        required: false
        type: number
        default: 1

the problem is there are around 8-10 different repositories which has their own workflows and I want to add this manual trigger to their GitHub actions

I want to avoid duplication by copy pasting same code to each GitHub actions. Is there a way to reuse the workflow. I have the image to create it as central file and then call this file something like that.

If it is not possible to reuse it is there a way to automate this like I define it once and it gets copies to all other repo files?
