Hiding empty bars on same stave

If I wanted to hide the empty piano bars like you might see in some contemporary scores, showing just the final bar where it comes in, how would I go about this? Is there a setting I can turn on, or would I need to just use a graphic frame with plain white in it? Thanks in advance!

May be an image of text that says 'A.Sax. Sax. molto bo like whisper poco sub. suh PP Pno PPP fade into nothing freely'

Dorico does not yet support cutaway scores, although there may be a (complicated) work-around.
