Number of zombies raised icon when using controller pad

Hello, controller option is really a good thing

but only 4 skill icon visible instead of keyboard having little much
i'm playing necro and need a icon to know how much zombie i have

is it possible to have invocation icon number ? or better just next the skills?

then we can play 4 skill without switcher LT or RT to see zombie on second panel of skills

THanks in advance :)
