[JASS] Read value from Ability

[Oncer]

Is there any JASS-Function to read values from Abilities?
A short example:
I have a custom Ability called "Stomp" (A001) and I want to use the Value "Area1" of this Ability in a trigger to make a nice effect in this area
How can I make this?
Is it possible at all?

You can't read a specific field from an ability.

You can only read the level of the ability which you can use to calculate an area of effect.
Use the Unit - Get Level Of Ability For Unit to determine the level of the ability.
