We have a custom GitLab CI-component that inherits from an upstream component (e.g. the official gitlab OpenTofu component). And there we inherit some version inputs and I want my component to update the default value of the upstream component's version. That looks like below:
Upsteam component:

---
spec:
  inputs:
    version:
      default: "1.0.0"
    ...
---
.component_job:
  ...

and in my custom component:

---
spec:
  inputs:
    version:
      default: "1.0.0" # this version should always be the same as in the upstream component
---
my_job:
  extends:
    component_job

I need to redefine the default version by gitlab. The problem is, that technically, in a component are always two yaml objects in one file. And the custom datasource of renovate doesn't work with this. So if I would merge the two objects to one (remove the second '---') then I works fine.

Is there a way to deal with two yaml objects in one file?
