Reference Chart By Name That Is Not On Active Sheet

I am trying to select cells, tables and charts by just knowing their name. Thus if possible I would like to only refer to a chart by its name i.e. not know what worksheet they are on. This seems to work for named ranges of cells/tables, but not charts (I can't get my named charts to appear in the "Define Name" dialog).

I found this code that loops through charts on the activesheet and shows the names. However, I would much prefer not to have to specify the sheet or to loop through all the sheets trying to locate the one with the named chart.

Public Sub GetEmbeddedCharts()
Dim myChart As ChartObject
Dim myCharts As ChartObjects
Set myCharts = ActiveSheet.ChartObjects
For Each myChart In myCharts
Debug.Print myChart.Chart.Name
Next
End Sub
