Is it possible to share only certain properties of an object across other pages?
For example, I have a text heading on each my pages. It's in the same place and same color on every page. The actual text differs though on every page (e.g. one page says Home, another says About, etc.). Is it possible to share it the color and location across other pages, but not the actual text value?
You can "cheat" this by converting one of the text objects to a button symbol. Button symbols allow for different text labels for each instance. I do this all the time. Use this symbol on all your pages, and update the label in the Properties panel.
One trick though, make sure you ad an identical Over state to the button symbol, otherwise if you preview or export an HTML prototype, the text will disappear if you mouse over it.
