I try to step a DC voltage source in transient analysis in LTspice. Below there are five almost identical biased transistor circuits and plots for 1 sec duration. The only difference is that their DC bias is is increased from 500mV to 900mV with 100mV increments. So this DC bias is the DC voltage source in the question(V1, V2, V3, V4, V5). I know that such step is possible in DC analysis.
As you see above, to obtain those plots I had to create five circuits.
Is it possible to obtain the same plots above by using only one circuit and writing a SPICE command in LTspice?

is your total simulation time, besides a simplePWL
that was already suggested and answered, you can add aPULSE 500m 900m 0 {t}
