hide cautionary clefs, keys and time signature

Hello everyone, I have xml file created by my colleague on Sibelius 7.3 with about 40 solfeggio examples for our solfeggio book. Every example is 8 bar long. And we really dont need cautionary clefs and time signatures. On Sibelius I just use hide/show function for cautionary clef and hide for time signature. That way my editing time is really very short.
On Dorico I have to rewrite solfeggio examples one by one in to different flow? For me it doesnt sound like good solution. And I would really like to make our book on Dorico.
