Would anyone know how to code a ComboBox self-reference, so that it could be used in a Combo Box processing procedure that was called from multiple ComboBox Change events, in each case referring to the specific ComboBox from which it was being called

For instance, in the below procedure I want to be able to use it in multiple ComboBox Change events and in each ComboBox, it will being making reference to its own value (ComboBox.Value), but not sure how to code to have each ComboBox make a self-reference that can be used in its code, but that is code that can be used in a procedure to be called from within multiple ComboBoxes?

Public Sub CBOItemProcess(
with WhatGoesHere?_that_could_reference_whatever_ComboB ox_the_procedure_was_being_called_fro
If .Value = "RT239" The
Call ThisProcedur
ElseIf .Value = "JY457" The
Call ThisOtherProcedur
ElseIf .Value = "WN2345" The
Call AnotherProcedur
End I
End Wit
End Su

Thank you for any assistance
