Workflow for scoring to picture (mainly tempo change)

So you’ve spotted the cues and you’ve scored to perfection.

Now the director gives you a revised cut and the lengths have changed slightly. One way to resize your cues is to tempo change to taste.

How do you handle tempo change? If I select all clips in the audio pool and put them to musical mode I get some grainy slushfest. I want to just slow the tempo a weeny bit for a cue so it fits the new length. What’s the quickest workflow to achieve this in Cubase?
