Is there a way to bulk send Zoho Sign documents from CRM?

Is there a way to bulk send Zoho Sign documents from CRM?

We use the Zoho Sign extension, and the documents are generated individually for each customer. The data is fetched by selecting the corresponding field from the drop-down.

We have a need to bulk generate documents, pulling data from each related Contact record. 
From what I can tell, the Send with Zoho Sign button in the mass update button section of the list view does not return values for each record, making it kind of useless unless you want to send documents with identical values. 

Is there a workaround for this? Thanks.
