Views: set a dynamic filter value

Dear drupal community,

I would very much appreciate your expertise on following issue:
I want to construct a view with following constraints:

  • Show entries from the content-type XY AND it is authored by the currently logged in user

OR

  • Show entries from the content-type XY AND the first field/column corresponds to the currently logged in user

OR

  • Show entries from the content-type XY AND the second field/column corresponds to the currently logged in user

I do know about contextual filters, but I cannot use them when I want to introduce OR with filter groups as they are applied on the entire view.

Is it possible to input a dynamic value instead of a hardcoded value? – in my case the currently logged in user:
enter image description here

Thank you and best regards,

Kale
