Filter for calculated field

Hello everyone!

In a filament table I have a field called TTF (Topical Trust Flow) which has a dynamic numeric value depending on the topic chosen by the user.

I would like to perform a filter on this value, but I need the filter not to be "custom" in the Livewire component page but rather to be a filament filter. The point is that this calculated field is not saved in the database and so I would not know where to retrieve this information with the classic
query
method.

Thank you very much for any help you can give me. Attached is the code for the column.
