This tutorial from 2017 has a Move Effect in the Format Polygon Symbol pane.
I've added a gradient stroke, but I don't see the Move Effect option. Where is it now? I'm on v. 3.5.2
Solved! Go to Solution.
You should also be able to apply it to specific symbol layers.
In general, Offset and Dash are automatically added to default symbols, but everything else you have to add yourself. Also, order matters.
