How do I override a mod load order or set manual dependencies?

I am using Enhanced Enemy AI SE and Blade and Blunt - A Combat Overhaul. The former recommends to load it after Blunt, but I can't find out where to do that in Vortex. I enabled the Dependencies column, but clicking the icon just says "no rules".

Two options, AFAIK.

You can do it through a drag-and-drop process in the Dependencies column on the Mods page, or if both have a plugin, you can do it likewise on the Plugins page.  I suggest going to the plugins page first, to see if the built-in LOOT has already arranged them appropriately.  Do not make the mistake of running a separate installation of LOOT, as it won't see the internal modifications that Vortex handles.

Be warned - the drag-and-drop interface can be very tedious, especially with long load orders.  You simply click and hold on the interconnect symbol for one of the pair of mods involved, and drag it to the location of the symbol of the other mod, a green arc will appear to show you are attempting this.  Be patient if you have to wait for the page to scroll as you approach the other.  You may have to try a few times to get the 'feel' of the interface correct.  A dialog box will appear, allowing you to set which one must load before the other, and Vortex may have to move both to maintain other dependencies.
