Displaying rolled up milestones in a summary project

[RonK]

all I have a summary project containing a number of sub-projects. Each
sub-project has rolled up milestones displayed. When I open the summary
project the only way I can get the rolled up milestones to display is by
expanding each of the sub-projects first.
Is there a way I can get the rolled up milestones to display automatically
when I open the summary project?
Thanks

Thanks Rabey but that's not what I'm after.

i understand about ticking the Roll up Gantt bar to summary and I have done
that on each of my sub-projects.

My problem is that whenever I open my summary project file none of the
rolled up diamonds display on the project summary bars. To get them to show,
each time I open the summary project file I have to show all sub-tasks for
every sub-project and then hide them again and in that way each sub-project
summary bar shows the diamonds. I was wondering how to get the diamonds to
show on each sub-project task bar automatically whenever I open my summary
project (without me having to show/hide sub-tasks every time).
