IEC or ANSI short circuit activities are for steady state calculation of short circuit studies, therefore, they do output only maximum values of currents without waveform since there is no time simulation involved.

As Cao Huy said, in a dynamic simulation, current rms values trends can be plotted. There is a channel (Iterm, available in the channel wizard menu) for the terminal current of a generator. For other elements, you can calculate the current (using functions in PSSPLT) from ready available channels (from P, Q flows, get S and together with V, calculate I)

Another option is to export channels to excel for further process and plotting.
