Sage 300 business intelligence reporting trees

We have created a report using the trees - which works

Now we have another scenaria with organic and non organic stores - the problem here is organic can consist of dept 11, 22,23,30 etc

Non organic 12,18,32,etc 

How can I drag all the trees into one cell - I cant create an all as it will then bring all accounts

So if I can somehow say PMB+DBN+ for example

Does anyone know how to do this please
