I've scanned in some maps, and I'm regularly adding little touches here and there to each map in Photoshop. Each map has a few Ps layers and is not vector.
For all the annotations, I'm using Illustrator, because it's better for the job with its typography tools.
In Ps, I can drag some graphics/layers in from Ai and it becomes a single 'vector smart object' so whenever I want to edit that graphic, it opens in Ai and updates in Ps when I save.
How do I have the equivalent of this in Illustrator? I have a multilayered graphic which I want to keep opening and editing in Ps but still keep at the exact same size and position in the Ai document (to keep the annotations accurate)?
