popup-only renderers for GtkComboBox

Description
It would be nice to be able to add renderers to a GtkComboBox that only appear in the popup (i.e. they're not shown in the button).
Here is an example of where this might be used:
A combo box offers a choice from a list of profiles. Each profile comes from a file. In the popup menu you want to show a preview, the name of the profile and the file the profile comes from.
The filename however is quite long and causes the GtkComboBox to expand horizontally. However once you've selected your profile, the filename is not very important, so it would be nice to be able to not show it.
