Style Sheet Concepts

Hi, 

I work designing learning tools for a software company. We are customizing elements (text boxes, shapes) to reflect our enterprise's current branding scheme (colors, fonts, etc.). I am wondering if there is functionality within Storyline that allows us to reference a central location for these custom elements, so that if our marketing department changes these elements in the future, we would be able to change the fill color in a text box, for example, at one central location and have it auto-update to all text boxes that have that fill color. Not sure if this is possible, but I thought it was a good enough idea that I would give it a shot. Thanks,

Matt
