Task ordering against WBS

Hi all,

Am I right in thinking that regardless of the sort order selected, within a WBS level the first items to be shown will be the activities at that level then followed by any lower level WBSs?

e.g.

WBS L2
Activity 1
Activity 2
WBS L3
WBS L3
WBS L2
etc.

Is there any way of having the activities appear after the lower level WBSs?
like
WBS L2
WBS L3
WBS L3
Activity 1
Activity 2
WBS L2

I know that I can create additional WBS L3 to hold the activities, but if I wanted a milestone under L2, summarising the dates from L3 then it appear first when I’d really like it to be afterwards.

Cheers
Jim
