Add 2 Vehicules


I have a question , is it possible to add a vehicule that i created in a other save in a new save ? I mean i builded something and i was like " wow it could be fun if i add an older creation to that " . But it s two differents saves . Is there a solution ?

1-Move machine number 1 away from machine number 2 spawn point (so they don't spawn inside each other)
2-Save machine number 1
3-View your saved machine folder(open load machine then click on the long gray text that ends with "/Savedmachines")
4-Open the file with machine number 1's name
5-Copy and every thing in it
6-Open machine number 2's file

i never did it so I'm not sure if it works

EDIT:There are extra steps after 7 but i don't know to to do them
