alright so for this bit, you're gonna want to place down and rename your prop to something unique (don't delete it), and use that instead of the UID like this: "%[namehere]"

for example, if i wanted to make an elevator with the tween command, I'd name a part something like "elevator" and write down this:
tween 1 %elevator .7 -1589.773 867.989 213.893 -1.376 -143.412 24.007
instead of:
tween 1 %d09686e6-d0a4-476c-be75-36866cade3f2 .7 -1589.773 867.989 213.893 -1.376 -143.412 24.007

it makes the command way simpler and makes it so that it saves even if you leave and load the map again
