Feature Request

[Justbob56]

I am working on an interface that allows deleting files over a selected age and would love to use the input_number on the right to set the maximum_files parameter for the card. This requires the card to allow templating. It would actually be a great service to make ALL cards templatable but at the moment only certain cards allow it like the custom:button-card. This would be a very useful feature for this card.
