Up & Down (+/-) keys for integer questions!

Is there anyway for Integer numeric fields to have a +/- button displayed next to them, for easy entry by tapping on a device screen rather than picking a number from the keyboard. We use KoboCollect to tally events as they occur. We are using the Range control but it is a bit awkward for numbers over 10 or so. We would like to be able to do something like the Cubes put in the Switch and Cubes put in the Scale questions shown in this screenshot: https://user-images.githubusercontent.com/9490724/38289412-e035efa8-378a-11e8-85cc-9de4d856c787.png
