Upgrading in generated campaign

[JaM]

To Developers: Can you look at uprgade sequence in custom campaign? In custom campaign after battle i can upgrade units after clicking at change button. it opens change units menu, when i upgrade unit,then i can upgrade other unit from unit list without exiting menu(just select unit on unit list).In generated campaign i must exit change unit menu and choose other unit. Is possible to make it similar in generated campaign? It is too boring, if you have big core unit, and you need upgrade 40 tanks...
