TTMSFMXMemo OnChangeTracking

I'm missing the TMemo OnChangeTracking event in TMSFMXMemo. The Lines.OnChange is not available because it is used internally. Of course I can modify the source, but this will cause troubles with updates. My temporary solution is a TTimer checking if Lines.Text has been changed, but I would prefer a built-in solution instead.

Or did I miss something?
