Need an "Accept" weapon customization button

Oftentimes during play, I will customize a weapon based on changing battle conditions.  I drill down 5 windows to get to the weapon customization, and then when I'm done, I have to back out of those 5 windows so I can get back to the battle.  This is annoying, so it would be great if there was an "Accept & deploy" button right from the weapon customization window.

Thanks for considering my request.
