No and Yes. No direct method, but you can write a script like this.
// Size comparison SUN - VY Canis Majoris
Star "Sun-like star"
ParentBody "VY Canis Majoris"
Class "G2 V"
This sets a sunlike star next to VY Canis Majoris.
This goes well with several stars. I have a script which sets several major stars and Sol in orbits around UV Scuti, currently believed to be the largest known star. These are not the orginal stars, so behind every name a (CS) (Comparison Star)
Exposure should be set low, for example 0.1 (F7 key)
Of course, the system chart can be accessed with the 0 key.
