Using Path to filter table showing only PathContains Data

Ok. I was able to resolve this

1. Created a disconnected table of the original table, lets call it tableB

2.  created a calculated column 'Path' in tableB

3. created an additional calculated table tableC, with union of 4 levels of pathitems eg. 

var _table = SUMMARIZE(tableB, Name,Parent,Path)
var _table1 = UNION(
    ADDCOLUMNS(_table, "Entity",  PATHITEM(Path, 1, TEXT)),
    ADDCOLUMNS(_table, "Entity",  PATHITEM(Path, 2, TEXT)),
    ADDCOLUMNS(_table, "Entity",  PATHITEM(Path, 3, TEXT)),
    ADDCOLUMNS(_table, "Entity",  PATHITEM(Path, 4, TEXT))
)
return
SUMMARIZE(_table1, [Entity],Name)

4. Created a bidirectional relationship between tableC 'Name' and tableA 'Name'

5. Using Entity as Slicer, I was able to create filter childs of that group.
