Abililty to Export existing BPM Approval Rules into Spreadsheet Approval Template

Summary: We are using BPM Approvals for Payables as of now but as this Spreadsheet Approval has come into play, we would like to know if there's a way we can export/download our existing BPM rules in a Spreadsheet Approval Template so that we can get to know how our existing rules look in that particular template.

Content (required): We need to know how the spreadsheet approval works and hence would like to check if there's any possibility of downloading the existing BPM Approval Rules in the spreadsheet template.

Thanks
