Hi @Mwe583!
To enable Snapping there is no need to go into the modeling mode, you can just toggle snapping mode by using the hotkeys Ctrl+Shift+S or the grid icon in the toolbar.
On the snapping menu through the toolbar, you can select to snap to Vertices, Pivot Points or Grid
To Snap to an actor or component to a specific vertex, you can hold the key V while dragging and it will snap to the nearest vertex.
You can also hold Alt+right-click on the object and select Move Pivot Here to place the pivot at any point you clicked.
Here is a video explaining Vertex Snapping.
It’s not as flexible as blender but I hope this helps.
