How to plot a single wave in adexl

[Problem]

I run coners simulation in adexl, and i get results of  waves.normally, I get a single wave if i double click a wave icon of one corner simulation.

But, if i run "sweep variable + corner" (configure variable values in "data view -> global variables"), once i click a wave icon, all same waves in other corners  are also displayed, which is really slow.

Does anyone know how to plot a single wave in "variable sweep + coners" simulation.

[I tried]

double left click, or "right click -> plot" display all wave. "right click -> main from.." can plot a single wave, but seems to be  troublesome for expression wave.
