saving custom data in map

okay i need to know if there is a way to save my data from a map i created.

example: i created a custom grunt to do 300 damage. i need all the data like this saved so i can import it into another map i create. sorry if confusing. thank you.

open the object editor, click file -> export all object data

goto your new map, object editor, click file -> import all object data

that will copy everything, units, abilities, items, doodads

you can also do each one seperatly if you want, as in, just import unit data.
