Three issues for which I have been unable to determine solutions:
In measure 16 of the music in the attached file, two soprano voices are both slurring. I’d prefer having both voices show slurs, but Dorico only gives one. Putting them in separate voices did not resolve the issue.
In measure 76, the sixteenth rest should precede the sixteenth B note. I’m probably missing a setting somewhere.
In the last three measures of the composition, caesuras should appear on selected staves with fermatas on the remaining staves. How to do that?
Without seeing your score, offering help is difficult. As a first time forum user, you will need to establish a “trust level” with the forum software in order to post attachments. Here are some guidelines how to do that.
With difficulty. Dorico requires that Fermatas appear on all staves. So you would have to fake it. There are a number of threads detailing ways to do this.
