As Paul mentioned, your best option is to restructure your UI. If you have more than 100 input fields for example, then break the input data into logical groupings with each grouping having its own card.
If you are displaying information or photos or something, just display the maximum you can including Headings, section headings, etc, and add a "Next" button to call the next card...
Cards and Card Service is very strict, similar to G-Forms, there is only so much you can do within the framework provided.
