How to add second name to custom keyboard layout, that appears on control panel?

Does anybody know how to add a second name for custom keyboard layout, that appears under the main name on the control panel, like US under ENG for “English (United States)”?

I made a few layouts for one language via MSKLC and I don’t see which I use looking on the control panel.

I assume that it can be done via “Registry Editor”, but I didn’t find anything except “display name” in path:ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlKeyboard Layouts0000409, but it’s not it.
