Modify individual borders - Group template

Guys,

trying to re-create this shape

and this is what i currently have

I’m using a Horizontal group with 2 auto panels (rectangle) inside, one contains the text and the other the nodes.
I will like to use the rounded rectangle but the line in the middle (between the 2 panels) doesn’t look like a line anymore, is it possible to handle the borders individually?

Instead of a “Horizontal” Panel with two “Auto” Panels, use a single “Table” Panel and you can control the separator stroke.

Thank you. will give that a try

Thank you Walter, your response and looking at this other question Table Panel with dynamic column widths

helped me figure it out.
