You may use two sources, setting one to zero one to the value you require.
This can be achieve with sweep and equations...

You need a voltage source U=0V or a current probe for that.

Yes. Should be a short in transient, isnt it?

Hmmm... Any volunteer here on the list?

You can output to PS...
Or choose a printer device which produces PDF.

Hm... Let's see :)
