We haven't added virtual instruments yet, but I will certainly bring this feedback up with our product management team.
You can however use reference probes to make differential voltage measurements rather than having to do the calculation yourself:
Reference probes can be found in the Probes subpalette and are used to specify your voltage or current measurement reference.
Here's how to use it:
Now the voltage measurement from your voltage probe will be the voltage across the component.

Great tool. However, do I transfer the design to ultiboard? How are custom components and foot prints handled?
Here is an interesting channel where you can find very important information in the Electricity Sector:

I see no one responded to your post. Sorry about that! From Multisim Live, you can export your circuit to Multisim (for desktop). Then, from Multisim (for desktop), you can transfer to Ultiboard. Hope this helps!
