Feature Request: Allow Placeholders in Overrides

Based off a conversation with @nitrada in #52…

The current behavior for using this plugin with symbols allows using the {...} placeholders within layer names (and layer content?) as such:

However, I’m in a scenario where I don’t want to lock my symbols (nested symbols here) to a particular block of data. For example, let’s say I have a grid and each column’s cells are nested symbols (like normal content, a dropdown, a link, etc). Then, each cell should receive a different property of the JSON data without locking the nested symbol to the given property. In this case, instead of having to duplicate or detach my dropdown or content symbols, it would be great to be able to specify the placeholder ({...}) within the override rather than the layer name like so:

This approach allows certain symbols, like the dropdown and link, to be agnostic of the data they’re being populated with.

@nitrada I think this should sum it up pretty well but let me know if anything needs clarification. I looked through the demo.sketch, which did illuminate some of the features a bit better but unfortunately I still couldn’t find a way to tackle this use case with the current feature set.

Let us know if we can support the thought process (why it makes sense, etc.) or support it in any other way! 😃

@skipjack @bottledsmoke @mhcom we’re trying to get this working for v3.0.3!
