It would be a great feature, if it would be possible to add a Milestone Workpackage by activating a Checkbox when a new Workpackage is created.

For example, I create a Phase Workpackage and it will result in an Milestone:
WP is “Produce Prototype Board” will be followed by MS “Prototype Board ready”

One problem I found is, if I change the End Date of the WP to a later date, it will move the MS also to the later date, but if I move the WP to an earlier date, the MS will be still at the same date. Why does the MS doesn’t move to the earlier date as well?
