In Craft Prototype, you can create a hotspot from a layer within a master symbol to any artboard in your file—even if that artboard is on a different page than the master symbol.
To create a hotspot from a layer within master symbol:
In your Sketch file, select the desired symbol layer.
To start an interaction, use the keyboard shortcut C.
At the top of the page, click Artboard. Note: Depending on your needs, you can also choose from Link Back/Close or External URL.
In the first drop-down, select either Link to a screen or Link as Overlay.
In the second drop-down, select the desired artboard.
In the third drop-down, select a Gesture.
If desired, select the Maintain scroll position after click checkbox.
Click Add Link.
The master symbol layer will then be denoted with a small blue arrow icon (), indicating that it is a hotspot. Anywhere that symbol layer is used on the same page as the destination screen, you will notice a purple arrow drawn to the destination screen.
Note: Hotspots are applied to all instances of the symbol—even those with overrides. Currently, there is not a way to disable this.
