Stacking items / Tight groups

Hello! I was wondering if there is any sort of way to arrange items directly next to each other. For example, you have 3 images but want them touching each other. Now, we are all probably familiar with Arrange which would allow us to 'align right' but that of course would move all of the images right. And if we distributed horizontally then it is all determined by how far apart the 3 images are.

My use-case in particular is making something like a file dropdown menu, where each menu item is directly next to another. There are the snaps and whatnot but there are so many objects on screen that it can be difficult to even get to the right one.

What I generally end up doing is doing math to figure it out:

box height * num of boxes - 1 + Y of topmost item, and then distribute vertically. But this only works if all of them are the same height.

So yeah, in short, is there something I'm missing that would allow me to quickly stack items in a tight group?
