Hello, I've successfully created a trivia game and passed certification with the help of the reindeer guide, however, since my game uses simple math I think it would be easier for the user to answer the questions as A, B, C, or D instead of 1, 2, 3 or 4. I'm currently using the number slot for my answer intent as guided. I don't see a letter slot option and I've also looked in the code but couldn't find where I would need to change numbered answer variables into possibly text shown as number variables. I'm still a bit new to Alexa and Lambda development. I've read that Alexa has trouble with single letter inputs but is that also the case with single letter answer responses? Any help would be appreciated. Thanks!
