Cards layout/Multi-line Question: show/hide elements of multi-line question conditionaly

I have a form in card format.  I would like to add a show/hide condition to the fields in a multi-line question.  I'm assuming it isn't an available feature at this time, since the individual questions were not shown as an option in the conditions "DO" field.

The field is "Children in the home".  The current questions are "number of children in the home", "age of the oldest child", "age of the youngest child".  If the show/hide condition could work within the field, I would like to add another question "age of the child" - so that if "number of children in home" = 1; "age of the child is shown"; if "number of children in home <1; "age of the oldest child" and "age of the youngest child" are shown.

Is this possible?

Unfortunately, it doesn't seem to be possible to hide/show particular questions of Multi-line Question at the moment. I can only suggest placing those questions on separate cards to show/hide them with the conditional logic. 

But, I will forward your question to our developers as a feature request. I'm afraid we can't guarantee when and if this would be implemented, but once we get an update, we will notify you at this thread. 

Thank you.
