How to add customised form fields to the attributes form

Does anyone know if its possible to add customised text strings to the attributes form in a product listing (large product view).

I have created a checkbox in a new product attribute but this checkbox also has two text string fields I need to insert that will define the checkbox subject.

i.e.

checkbox  = ticked  |  text string [name]  |  text string [number]

Thanks
