This is a silly question but it's bothered me for a while and I finally can't figure out a workaround.
How do I drag units to drop them in something that doesn't show up on the screen without scrolling? So, for example, I want to drag some artillery from my Replacements formation to drop into 1st Division, which has suffered casualties. Replacements, though, shows up at the bottom of Earth's very long list of forces and 1st Division is at the top. I can't seem to scroll once I'm "holding" something so it has always seemed to me that I could only drop things into something that shows up on the initial screen without scrolling.
For navies, I solved this problem by just creating a lot of silly Admin HQs and Fleets that can always be collapsed.
But I can't seem to do that with ground units. Each HQ has to be built. Since I only have division-level HQs right now, that means 25 divisions are shown on Earth. Not to mention all the survey battalions, mineral battalions, and construction battalions, that don't have division-level organizations.
There has to be some basic interface command that I'm missing.
