Request for duration adjustment at slur end before rest

Although happy with playback overall with Dorico / NotePerformer, I’d like an additional option for the ends of slurs before a rest. There should be a difference in sound between a slurred passage and a succeeding note on one hand and a slurred passage and a rest on the other. It would be useful to adjust both the shortening at slur end in general and the shortening preceding a rest. I realize I can adjust the played durations in the Play window’s piano scroll (and elsewhere), but doing it once per project (?or flow) would save time tweaking. I think the user should have control over this function because the amount of shortening would vary depending on tempo, style and taste. If it exists and I’ve missed it, apologies and please tell me! Thanks.
