Thank you for your post, and I apologize for the late reply.
At this time, the Choice value list is controlled by iOS. Since what you are asking for is a design change, I encourage you to enter this information into our Feature Requests web form at:
The entries into this web form are monitored and read by our Development and Product Management departments where the entries are discussed and considered for future releases. Although I could copy your post and paste it into the web form, there are a couple of questions asked that only you can answer.
Done, finally. Sorry it took me so long.
