Excluding an url rather than a domain

[nsa]

I wonder if it is feasible to exclude an url rather than a whole domain. For example, I would like to exclude my twitter profile but I don't want to exclude whole twitter profiles.

Maybe an option like exclude_url could be implemented for this.

nofollow:
  enable: true
  field: site
  exclude:
    - 'exclude1.com'
    - 'exclude2.com'
  exclude_url:
    - 'twitter.com/myprofile'
