Hello all,
I have this dataview where the products are on the rows.

There are a couple of columns that are higher level entities:

Now there's always the possibility to select by the rows' axis in the context menu of the dataview.

I would like to expand that feature, by means of procedures, and build a context menu like the following:

Now the first one is done easily. It's just a two step procedure with "Apply selection to screen" and "Refresh screen".
Is there a way to make a selection broader? In my example instead of filtering on the product, filtering instead on the product group. Product and product group are part of the same tree.
BR, Ray
