Enable Bulk Signing for High-Volume Envelopes

Customer is helping a vendor to send docusign envelopes to (est.) 10,000 clients. After each client completes their docusign, they’re considering routing the envelope to the supplier. But this only works if the supplier has the ability to complete dosusigns in bulk.

It will be good to have a feature/setting/capability, on a special project basis (not an ongoing process basis) that would allow the vendor to complete 10,000 docusigns in bulk (instead of clicking through 10,000 emails?)
