Don't know about CentOS6, but with CentOS7, the selection of apps that 
you can use appear to map to '.desktop' files?

If it is the same on CentOS6, then you might be able to set up a 
suitable .desktop file (e.g. in /usr/share/applications/ or similar) to 
do what you want ...

No idea if this is of any help
