[Mobhack]

I only ever use the one FOO, and but it as the first unit so it always appears just after A0 on page 1 of the 2 roster screens, so its easy to find rather than scrolling all over the map.

The same would still apply if you want several FOOS - buy them all first then they are at the start of the list so easily found via the HQ menu screen listing. You could then say keep a mental list in your head - #1 is at the top of the map, #2 is somewhere in the middle of the map and #3 is the one deployed down south say.
