customize default visual settings

Is there a way to change the default settings in Power BI? For instance, I like having a very light grey border around my visuals, but I have to change the color every time I create a visual from black to the light grey. Is there a way to make it so when I turn the border option on, it automatically appears in light grey instead of the defaulted black? I know this seems like a dumb request but changing the border color for every single visual is soo tedious.

Thank you!
