Node Position or Location based off of Node part and not Node itself

Hi, Long time listener, First time caller…lol

My question is, is it possible to position a node via location or position based on the Image part or any sub-part of a Node, or only the node itself? My issue is I have a node with an image in the center, this image has a standard size, but has other attributes such as ports, and annotations. The annotations can be on top, bottom, left, or right based on a users choice. Problem is once a annotation is loaded at the top of a node, the image isn’t lining up with other nodes that have a annotation at the bottom of the node.

Stubbed out code that resembles my current code.

$(go.Panel, “Table”
{},
$(go.Panel, “Auto”,
{ row: 1, column: 1, name: “BODY” },
),

$(go.Picture,
	{name: 'nodeIcon', row: 1, column: 1, width:36, height:36, stretch: go.GraphObject.Fill},
	new go.Binding("source"),
	new go.Binding("position", "position", go.Point.parse).makeTwoWay(go.Point.stringify)
),

//adding left ports
getPort($, "leftnode")
//adding right ports
getPort($, "rightnode")
//adding top ports
getPort($, "topnode")
//adding bottom ports
getPort($, "bottomnode")

//annotation panel

$(go.Panel, 'Auto' {},
	new go.Binding('row', '', getRow),
	new go.Binding('column', '', getColumn),
	$(go.Shape, 'Rectangle', {fill: bgColor, stroke: 'gray'}),
	$(go.TextBlock, textStyle()),
)

)
