Add filter to Page


I need to filter "Standing Orders" by "Customer Group". But "Customer Group" is a field for example in the "Customer" Table and no filter option or field in the "Standing Order" page/table.

I read on this page here TIP #35 | Using Queries in Pages & Reports, but I'm not sure if this will solve my problem, since I would have to copy the hole "Standing Order" table to a new buffer table if I understand this right. I although read about Query and Flow Fields, but now I'm confused about the way to take. 

The new page "Standing Order" with the "Customer Group" filter should be available for other users, too.

Can anybody tell me how I could solve this?

Thanks and regards,
