How to save the signals in waveform window?

 Hi, I'm a newbie in NC-verilog field.

After launched the simvision, I sent some signals to waveform window from Design Browser window.

Before I quit the simvision, how can I save the signals info in waveform window, so I can load this info next time I run the simulation with simvision, instead of drawing these signals one by one from Design Browser window again.

 What's more, I wonder if there's a script way to specify which signals should be sent to waveform window. Then the specified signals will be added to waveform window automatically every time the simvision is launched, just as tcl in Modelsim?

 Thanks in advance!
