Is there any way for VS Code to indent to an open bracket?

There is a closed issue on GitHub for this very feature. A recent comment from the development team reads as follows:

This feature request will not be considered in the next 6-12 months roadmap and as such will be closed to keep the number of issues we have to maintain actionable. Thanks for understanding and happy coding!

Therefore, it will not be included in the foreseeable future.

The only option right now would be to attempt to create an extension that does exactly this or even hack on the main editor source code. I suggest you start here: https://code.visualstudio.com/docs/extensions/overview
