2018 Sequence - Tool To Unmerge?

Either due to a bug or a fat blond ( me ), this sequence is messed up. Every other pic shows the left camera and those inbetween show the right ( aka left cam-right cam-left cam-right cam-et al ).

Is there a tool for splitting those? This is an edge case. But more often just being able to set a split on an existing sequence of mine would be pretty handy.
