I need to recreate my company’s design system for use in Axure and would like it to be as flexible as it is in Figma. Specific problem I’m having currently is to make a button that resizes but keeps the content centered. Obviously I can create a new button widget or create a button using the label widget and setting padding, BUT I want to allow for buttons to have an icon and maintain its dimensions and spacing, both within the button and relative to the text. I’ve tried several approaches but keep coming up short. Thanks in advance for your help!
Recreating design system components
This flexibility of widgets/ components is something the Axure Team has still to work on in San Diego 
It also makes sense to orientate a solution on what the folks at sketch, figma/ adobe are implementing right now https://designstrategy.guide/design-system/design-tokens-101/
