Can you use variables in automated new topic titles?

I think it might be possible to add more placeholders:

plugins/automation/lib/discourse_automation/scripts/topic.rb

main


      
          placeholder :creator_username
          placeholder :updated_user_username, triggerable: :user_updated
          placeholder :updated_user_name, triggerable: :user_updated
          
          triggerables %i[recurring point_in_time user_updated]
          
          script do |context, fields, automation|
            creator_username = fields.dig("creator", "value")
            creator_username = context["user"]&.username if creator_username == "updated_user"
            creator_username ||= Discourse.system_user.username
          
            placeholders = { creator_username: creator_username }.merge(context["placeholders"] || {})
