That's awesome, and League Dominator is the best tool in FF by a mile...
That said, it doesn't seem to handle dual designations in my Sleeper league... I have Quincy Williams (DB/LB) and Jonathan Greenard (DE/LB) there, and it only treats them as LBs... so it's always telling me to start Chase Young (on IR) and pick up a DB to start, while telling me not to start Wiliams and Greenard.

Again, incredible tool that is exactly what I wanted, and nobody else provides anything comparable... which means it's worth fine-tuning to be perfect.
