Customize sender of email sharing a report to anonymous or group name

[Anonymous]

Is there a way to change the title of the shared report email from "John Smith has shared Power BI Report 'Widget Analytics'" to something less personal like "Widgets Group has shared..."  or even just "Power BI Report 'Widget Analytics' has been shared with you"?  When sharing with large numbers of O365 distribution lists, not everyone wants their name to be included.

Well, you are doing the sharing so your name is picked.  Have you tried changing the support contact for the dataset to see if that maybe gets picked up for the sharing message as well?
