@Tamas Hajdu Apologies for the delay on this, I was checking with my team on your ask.
With the current options we have, as you dont want to go with sharing a workbook option, best solution I can think of for now is to export the queries to PowerBI and produce better looking reports there.
Also you can share your feedback over here - https://feedback.azure.com/d365community which is closely monitored by our product group team.
Let me know if you have any further questions, feel free to post back.
