How can I use the enter key to change focus in App Designer?

I am creating an app in App Designer with several input fields for variables and want the enter key to be synonymous with the tab key. That is that pressing enter on the keyboard will move the focus to the next input field as tab does. I was going to use uicontrol, but this isn't supported in App Designer. Are there any workarounds?
