A runner for multiple projects

GitLab CI/CD
1

Hello,
I want to set up a runner for several projects. I created an empty project and in it I created a .gitlab-ci.yml file with the following contents:

include:
  - local: '.Project1.yml'
  - local: '.Project2.yml'

I created YAML files in the main directory of this project. The contents of each YAML file is something like below:

stages:
  - build
  - deploy
cache:
  paths:
    - node_modules/
build-Project1:
  stage: build
  script:
   - scripts
  tags:
    - Tag1
deploy-Project1:
  stage: deploy
  script:
   - scripts
  tags:
   - Tag1

With this, can I reset the runner for just one of the projects? For example, reset the deploy stage for Project1.

Cheers.
