Clock input mark for asynchronous registers

It's possible to set attribute "Trigger" to "High level" or "Low level" for flip-flops and registers, so components becomes asynchronous (transparent). But triangle mark for clock input is generally accepted to mean clock (synchronous) input exclusively. Asynchronous memory device should have enable input only (accustomed mark for it are 'E' or 'G'), so I suggest to remove "en" input from asynchronous flip-flops and registers and to turn clock input to enable one with corresponding mark change.
