How to change macro icon?

Question

Macros

Greetings! Tell me, please, is it possible to change the macro icon that is in the ribbon to your own image? Specifically the button becomes in Outlook'e. I rummaged through the Internet for a long time, found the Ribbon XML Editor program, but as far as I understand, this can only be done on a specific document (word, excel, access) and specifically for "myself".
And it is necessary that this can be implemented in the future by most users.
Thanks in advance! :)
