tabs-group-by problem

[molcomp]

Hello,

I am trying to resolve this problem but I cant figure out which way. The following is the situation:
I have 3 tables in a relation. In the first table projects in tabs is set by field project name and under group by is set to the joint field of the second table activities. Relation table contains name fields of both tables. Table project is joined on relation table.
List shows fine for the projects something like this:
Project1|Project 2| ...
Activites
Activity 1
Activity 2

Now the problem is that I would like to display field project summary that is inside the project table( this field does not exist in the relation table) . When I click display this field in the above list the field data are displayed under group something like this:

Project1|Project 2| ...
Activites
Project summary, Activity 1
Project summary,Activity 2

and I would like to achieve the following
Project1|Project 2| ...
Project summary
Project start date
Project end date and to show other fields inside the project table but above the relation table data and below tabs.
Activites
Activity 1
Activity 2

Hope I explained it properly. Thanks anyone for the help.
