Reuse plugin on specific routes, not duplicate

Hi,

I have the following configuration:
serivice A:

  • route A1
  • route A2
  • route A3

service B:

  • route B1
  • route B2

I want to configure OIDC plugin on routes A1, A2 and whole service B. I could not find a way to reuse a single OIDC plugin instance. Should I duplicate the OIDC plugin and configure each one separately? I would like to use a single instance of the plugin configuration, it is easier to maintain.

Thanks!
