I'd like this, too. In my case, the situation is that I've sent something for sign-off (milestone: 'x sent for sign off'), so I need to leave at least x number of days for the review to happen before the next milestone of 'x signed off'.

The only way I can see of doing this at the moment is to put in a task of 'client sign off' and using it to connect the milestones, but this skews the effort calculation on my side.
