Brep Topology Data Tree

Hi all,

I'm struggling with how to use the brep topolyfor reordering a data tree. For clearity I have made a simplified example of the problem:

Suppose I want to populate the edges of a brep with a random amount of points at random intervals, and aterwards i want to group the resulting lists of points according to the faces of the brep?  See Image.

Although  brep topology FE gives me all the indices of the edges for each face, i'm stuck in using those indices to reorder the data tree.

For the simple example I found a workaround, by using tree branch and path mapper, but this only works because all my faces have exactly three edges.

Any pointers?
