This is not possible out of the box because some reports still use the old Custom Layout Reporting (CLR) codeunit instead of the newer Document Sending Profile. CLR does not allow you to modify the email content when clicking "Send."
If the report request page includes an Output field, it indicates CLR is in use. This is why you can modify the email and change the "From" email address when sending sales invoices, but not when sending customer statements.
Your options are customization or use a default "From" email address. Can you clarify why you need to change the "From" email address instead of using a single default address?
