Clipboard Filter Macros available only when Clipboard History Switcher is Active?

I would like to hide/disable Clipboard Filter macros so they do not show up, for example, when using Trigger Macro by Name action. Is there a way to make them only available to Clipboard History Switcher?

I'm having trouble since the Clipboard History Switcher window isn't an application and its window title isn't recognized to enable/disable a Macro Group. Using AppleScript, I can manage to determine if Clipboard History Switcher is visible, but that doesn't seem to help me.
