Request ability to completely remove any png attachment to subscription emails

Idea:
I have users that believe the attached png file in emails they receive is what they must click on to open the .pbix file, despite having a sizeable golden tab in the body of the email to click on to obtain the report.

Is there a way to altogether remove any attachments from subscription emails? A PDF file might be more helpful. I would still prefer an ability to remove all attachments on some reports to force users to select the gold .pbix button. Removing the attachments will ensure users open their service with the gold button and review reports/dashboards for full functionality.
Thanks,
Dave
