Phased release - change percentage of users

The feature of phased release is very useful for our company, but a big minus for us is that the 'Percentage of Users' starts very slow, and at the last two days it's go up very fast.

For now what we can do is to start the phased release, pause it after 50% of users get the new version, and after a weak - resume the release.
I know it's not the purpose of the pause/resume but we want a better control at the percentages/days of the phase release.
Is it possible to change those somehow? Change the percentages per day/ change number of days for the phased release?
