Delete a partially signed EchoSign Document without notifying all signers

Hi,

We use EchoSign to sign forms and the final department that receives the forms was simply downloading them and not signing them.  We have since omitted them as a signer and download it ourselves and email them the form with our departments signatures.

However, now I have about 80 documents that were never completed in EchoSign, and will never be completed.  Is it possible to delete them without notifying all of signers?  I haven't done so yet because I don't want to inundate the signers with a bunch of cancellation emails and confuse/annoy them.  So the incomplete d just sit there, but it would be nice to clear them out.

Thanks,
