Resize Signature Box

Hello,

I work for SpringCM Support and we integrate with Adobe Sign in order leverage electronic signatures on SpringCM hosted documents.  We've had several customers request that they be able to resize the signature field, as it has a tendency to obscure lines within a document being sent for signature as it is currently only available in a single size.  All other available fields appear to be able to be resized at will.  We'd like to request that this be made available on their behalf.  Is this possible?
