How to achieve dynamic Attachment in Notification Rules

We have implemented a step transition workflow in Oracle Configure, Price, Quote (CPQ), where notification rules are configured to send email communications to approvers and sales representatives at different stages. Each notification currently uses a predefined email template along with a fixed attachment.

We would like to enhance this setup by making the attachment dynamic. At present, the notification rule only allows selecting a single predefined attachment, and it does not support scripting or conditional logic to vary the attachment based on quote data.

Our requirement is to dynamically change the attachment (for example, use different printer-friendly XSL templates) based on specific quote attributes such as the customer.
