App Development- Feature Edit

We have a functional, educational mobile app made with Unity 2d but want to change two features before we release it. Specifically, (1) We would like to make the Date selection on the timeline on the right of the screen multiple choice (by adding 4 yellow dots on the timeline, one of which is correct). The correct answer is drawn from a database and the 3 incorrect answers would need to be generated by an algorithm. (2) If feasible, we would like to make the location selection on the map multiple choice by adding icons on the map for 4 possible answers. The correct answer is drawn from the existing card database.
