What you can do is create a new Rich Text item or select an existing one and then append the contents of the first item to the second item using the AppendRTItem method.
Below is an example from the Designer help:
Dim docA As NotesDocument
Dim docB As NotesDocument
Dim rtitemA As Variant
Dim rtitemB As Variant
'...set values of docA and docB...
Set rtitemA = docA.GetFirstItem( "Body" )
Set rtitemB = docB.GetFirstItem( "Body" )
If ( rtitemA.Type = RICHTEXT And _
rtitemB.Type = RICHTEXT ) Then
Call rtitemA.AppendRTItem( rtitemB )
Call rtitemB.Remove
Call docA.Save( False, True )
Call docB.Save( False, True )
End If
