Main and white logo versions for sponsor logos

Hello, It would be very helpful if we had the option of alternating between main and white png logo versions for sponsor logos, as we have for event logos. I was using a dark background for our individual sponsor page headers, but this caused many of the logos to disappear, so my only workaround was to change the background to a lighter colour so the logo would standout enough.

Also, if we had control to make the sponsor logos bigger on the individual sponsor pages, this would be helpful, too. You wouldn’t believe how fussy executives can get about their logo sizes!

Thank you!
