I don't believe there's a supported way to do this based on the registry entry values and where they come from:

that are used to show that data, and the fact that the MSI ProductName property is fixed text that I think you can't change after the install has started. You could test that of course by simply using some script or a custom action to set the ProductName property to [ProductName] plus [INSTALLDIR].
So you'd have to update that Registry item in the Uninstall registry data yourself. At the very end of the install when the entries are there modify them with custom action code by appending the INSTALLDIR value.
It's not something that people do with MSI setups and I wouldn't recommend it. The value will probably overflow the field length because ProductName is limited to 63 characters.
If the issue is that there may be several uninstall entries and you want to verify that the user is uninstalling the right one, you could probably add some dialog to show the actual version somehow if you save that install location somewhere. The ARPNOREMOVE property will prevent direct uninstall, then you can force a Modify dialog to do Change and then Uninstall with more detail. The general idea is here:
