How to extend block.block.* schema configuration file Someone know how to exend this schema located in block module in core, to add a new data type in mapping from my custom module?

The point is that I need to add a Boolean field for all the blocks in the block configuration page and store this value (0 or 1) in all the block configuration files, but the problem I have is when I import the configuration for those blocks that does not  import the boolean field.

I guess I'm missing declare a "data type" for this boolean field.

    block.block.*:
      type: config_entity
      label: 'Block'
      mapping:
        id:
          type: string
          label: 'ID'
        theme:
          type: string
          label: 'Theme'
        region:
          type: string
          label: 'Region'
        weight:
          type: integer
          label: 'Weight'
        provider:
          type: string
          label: 'Provider'
        plugin:
          type: string
          label: 'Plugin'
        settings:
          type: block.settings.[%parent.plugin]
        visibility:
          type: sequence
          label: 'Visibility Conditions'
          sequence:
            type: condition.plugin.[id]
            label: 'Visibility Condition'


I want to add this

   mapping:
    hide_for_campaign:
      type: boolean
      label: 'Blocks hidden in campaign page'
The answer is to use the ThirdPartySettingsInterface Interface, using that interface you can add/save custom configuration for config entities, works perfect. Thank you !.
