A custom slot may contain a vast number of possible answers say 1000, however in a particular instance only a small subset of those answers may be relevant for a particular interaction say 4.
I understand it may be difficult to generate a custom slot with 4 answers on the fly, but would it be possible to reduce the number of answers from 1000 to 4 for a specific interaction?
