Get Alert Name through expression

Is it possible to read Alert Name through expression?
I can get Documentation Text like that (see attachment), but what about Alert Name?

I have numeric label showing values from a sensor.
I have several alerts associated with this sensor.
For example sensor tags path always start with PI21:
PI21_4mA, PI21_HighPressure, PI21_LowPressure.
Client wants to see alert texts with mouse-over text.
So I would like to change only one custom property, for example “TagName” from “PI21” to “PI31”,
so tags paths would be PI31_4mA, PI31_HighPressure, PI31_LowPressure,
and get all alerts texts associated with PI31 sensor.
