When I use the official Map Editor from GTA V then it seems that you are only able to test the Map from the Start Point all the time. This is very annoying when you build a hardcore difficult Map and you don´t want to start all the time again from the Start Point.
Is there a way to start the Race from as example Checkpoint #3 instead of always from the Start Point? I think there must be a way because I can´t imagine that hardcore difficult Map Builders always restart the Map from the Start Point..
Btw I can't ask the question at rockstar forum because you need to be 1 month online with your account before you can ask questions.
