How to customize Web URL in the Attachments

Hi Team,

In the Collections Workbench, there is an option to add attachments, we can add URL but is there a way that we can pass value dynamically.

Select the Transaction tab and we have select Invoice(INV_123), then click on Attachments paper clip and then add a URL such as google.com/INV_123.pdf,

INV_123 is the Invoice Number, which should be changed to dynamic, LIKE @INV, so that the selected transaction should show up here

Regards,

Pavan.
