Cancel a support waypoint, how to?

[splatsh 10]

If I give a medic a support waypoint with:

wp08 = _spawngroup addwaypoint [_cpos, 0]; // Position player
wp08 setwaypointtype "SUPPORT";
wp08 setWaypointSpeed "FULL";
wp08 setWaypointStatements ["true",""];

How to cancel that wayoint and give it one other waypoint, one "MOVE" waypoint for example?

I did try this, but it did not work:

wp09 = _spawngroup addwaypoint [_cpos, 10]; // Position player
wp09 setwaypointtype "MOVE";
wp09 setWaypointSpeed "FULL";
wp09 setWaypointStatements ["true",""];

deleteWaypoint wp08;

Unsure as to whether this will cancel the actual move order at the support position.

deleteWaypoint work fine =)
