barron It's not possible to split out code in this way, however there are some options for doing something like this.
For the Move Character function specifically, there's a third optional parameter that indicates whether the script should wait for the movement to complete before proceeding. This defaults to true, but it can be unchecked on the visual node to accomplish what is being described.
For example, this will move all three goblins simultaneously since the "Pause" option isn't checked:
More generally, you can also use the Execute Script function if you want to trigger events to run in parallel with each other. Its "Pause until complete" parameter works in a similar way and is disabled by default. Hopefully that helps!
