Repeat Grids are a great way to quickly repeat elements and keep everything in sync. However, they can also be used to quickly set up Stacks. When using components, a Stack is often a better option than a Repeat Grid, because the components themselves remain in sync.
To do this, select your component and enable Repeat Grid. Draw out as many instances as you need, and then click Ungroup Grid. Before you click away, all the elements will remain selected, yet ungrouped. Hitting Command or Control+G will group those objects together, and then you can enable a Stack.
