Button Group Editing

Love BTT to customize my touch bar..

Was wondering if there was a way to have the ability to edit all touch-bar buttons within a button group.. For example, I have a button group where I've stored a few touchbar buttons opening various apps. I would the option to set all touchbar buttons to an equal width of my choosing.. At the moment, if I wanted the touchbar buttons to be a non-standard, but uniform width, I have to reset each width manually..
