How to modify command in Gnome?

[Linux for blind general discussion]

Hi,

when I want to run Chrome with accessibility enabled, I must open with 
alt + f2 and type this:

/usr/bin/google-chrome-unstable --enable-caret-browsing 
--force-renderer-accessibility

is it possible to modify to this command under gnome-shell app panel? In 
Mate, Mozo app can be used.

Thanks,

Pavel
