So, correct me if I'm wrong but from what I've heard, that would be possible. However, it's based on the district, not state.
From what I've researched, there can be 5 spots allocated from congressional nominations in each district. However, because there are 10 nominations given in a slate, there may be 10 people appointed from that district from other nominations (ex. Presidential/Vice Presidential).
Of course it would be pretty rare considering usually only 1 or 2 nominees from the slate are given appointments, but I assume it would be possible for an entire state to have a total of 50 appointees.
