edit Master Styles for text AFTER they have been created.
Create editable Master Styles for text AFTER they have been created.
This way, you can change your mind about a title or subtitle after the fact, change the style, and it will reflect everywhere that style is used.
Unless I am missing something, what you are asking for is how it already works. I left some detailed info in the body of the User Voice thread you started. Thanks for your support.
Please take a look at the explanation. This is not resolved.
I just got off with Adobe Support and they confirmed that what I'm asking for is not possible.
What we would want to do is modify one of the Master Styles after it has been created instead of creating a new Master Style. That way, we could have a Title, Subtitle, and even more text on ONE text layer to keep our project layers manageable. Then, we can say "I want to adjust the font on the subtitle throughout the film" and CHANGE the subtitle Master Style. Just like in other graphics software and even Microsoft word, we should be able to create and define a style and then ALTER it as needed later.
Unless I am missing something, what you are asking for is how it already works. At a basic level, this is how it works:
1. Create a Master Text Style from an existing text layer
2. Assign that MTS to other text layers by using the Master Styles pulldown or by dragging and dropping the MTS from the Project Panel onto other Text Layers and/or whole Graphics
3. Make a style change to a layer which is a child of that MTS or a sibling
Result: The Up / Down arrows light up next to the Master Styles pulldown
4. Press down arrow to Sync from Master Style
5. Press up arrow to Push To Master Style
Down arrow: The text layer you changed is reverted to its previous appearance since that is still what the MTS item in the Project Panel looks like
Up arrow: The text layer changes you made are sent back to the MTS in the Project and to all sibling layers with that MTS assigned to it.
In this way you can change the style in one layer, press the up arrow, and it will reflect everywhere that style is used. Is that not happening for you?
