My choice for this is the Pedro's BB socket holder which will work on both style bottom brackets. There are other bottom bracket tools with this feature built in like this one, although I haven't seen one that does both types of bottom bracket, so you need two tools if you have multiple bikes with different bottom brackets.

Park suggests a quick release skewer but that would only work on bottom brackets with a hollow spindle.
