The most effective way to do this is use the true N S E W Macro from Walljump Position Helper Macro and aligning it to .001-East and wall jumping from the position shown in the video below. You can get other values to work, but it's much harder.
Stage 6 - Past AB Gates, Alliance 2.3.2
I know there are probably easier methods to doing this - but knowing a different approach doesn't hurt.
Edit: Yea this works in 2.3.3
