Choose One - Dropdown list instead of Radio Buttons

For a number of projects I use a generic Final Builder script. The top of which performs a "Choose One" where the project to build is selected.

This list is starting to get big and the radio button list is filling up the whole screen so that the Ok/Cancel buttons fall off the bottom of the screen.

Is it possible to make the "Choose One" control show the list as a dropdown list rather than radio buttons?

Rather than using the Choose One action, try the “Enhanced Prompt for Variables” action, it can display lists as combos.
