Aligning custom ButtonTypes

How do I make sure my custom Alert button is placed alongsode the cancel button? As of now, the cancel button is shoved to the right, while my custom button is put in a weird place that is neither left, right, nor center. I want all of them be right-aligned in this order: first my custom button, then the cancel button.

ButtonData.RIGHT puts the custom button in the cancel button's place. Not acceptable.

The custom button is semantically not a cancel button, so setting its ButtonData to CANCEL_CLOSE is not acceptable either.

More broadly, I want to avoid attaching any wrong semantics to the custom button just for the sake of alignment (e.g. OK_DONE). OTHER is as good as it gets for my case.
