Break all spline knots

Hi Guys,

What I'm looking to do seems like it should be very straight forward but having done multiple searches over the last week I cannot seem to find an answer.

In short all I'm trying to do is break all thespline knots of a selected spline. This would be for an Editable spline modifier.

Basically create a circle spline, add an editable spline modifier, select all knots, break knots, exit subobject mode.

Any help would be most appreciated.
