double integration with absolute value with integral2

How can I compute a numeric double integral of a function f(x) of the form int(|int(f(x)dx)|dz) with x that varies from 0 to z and z that varies from zero to a constant t? It is possible with the command integral2?

I think, no. You will have to use "integral" twice in a nested manner.
