FORMS 2.0: Field positionning with progressive profiling: field to position after progressive profiling box

We have created a serie of forms to download documents, using progressive profiling. 
We would like to add an unsubscribe field at the bottom of the form. 
Unfortunatly, because of the progressive profiling, this field doesn't appear at the bottom of the form (but in the middle, because 2 fields are required from the progressive profiling section).
It would be great if we could "force" this positioning to the bottom of the form, without using a specifing coding (since we are using this a lot, at corporate and in the subsidiaries). 

We have this issue with the unsunscribe field, but in general, for any field, I would like more control over positioning.
