Good Morning Maggie & James,
Certainly. James, I use the invitation lists to assign registration types out all of the time. It is very handy, assuming you are okay with managing multiple lists.
You can also set up your 'extra/additional' session as was mentioned, include it within an alternate Admission Item, and allow your end-users to self select the Admission Item that is a best-fit for them. Perhaps one could be named Executive Registration while the other is General Registration.
If you want to go a route that is a little more 'controlled', you could create/utilize two separate links/buttons within your invitation email: the standard button could be used for non-executive registration while a secondary button/link could be powered by a weblink that you create under your Marketing tab. See screenshot.
