IF, you are referring to the "Pedigree" 'View" (page/screen); THEN, you cannot.
Whereas, you can see the Children listed, generally without having to expand the list, on the "Person/Details" page/screen, for each individual/person.
That said ...
If there is more than one Spouse / Wife (Partner), you will have to expand the list of Children for the subsequent "Couple" Relationships.
You can select ONLY one "Preferred" Relationship at a time.
I hope this makes sense; and, helps.
Actually, if you click on one of the parents in the pedigree chart, the fly-out that comes up showing a summary of that person has a "Tree" link. If you click on that link, it will redraw the pedigree to show the tree with THAT person at the root, with all of their children expanded to the left of them on the chart.
Would that meet your need? If not, then while in the pedigree view with these parents at the root of the tree, try changing the view to the descendency view. There you can more easily see the inverted tree looking back toward the present.
