Is there an option in place for adding external links to purchase orders?  We send .stl graphics files from our digital scanner to be designed and then our vendors finish the design and return the finished product for use to manufacture.  We would like a process flow for this and integration with workdrive.  Currently we take the .stl file and upload into WeTransfer then copy and paste the url download link into the purchase order and send to our vendor.  Is there a better faster way within Zoho?  Thank you.
