Is this scheduled to be added in an upcoming version of MIPSDK?

In the 2018R1 coming shortly you can now work with time profiles, user-defined events, analytics events and generic events. This a step towards also being capable of supporting alarm definitions. Alarm definitions will be added but right now there is no schedule which can be announced.
