divisi on two separate staves but only temporarily

so far, i've just been using the voices to create divisi. however, because the two parts are so different, it looks kind of confusing on the same line. i was wondering if there was any way to split only the divisi sections onto separate lines, kind of like how a piano part looks. i know that you can add in a second clef into a part and use that as a second line, but that second line stays for the entirety of the music. is there a way so that the second line only appears when i need divisi?
