question about sidebar

I have a question about the publisher theme,

there is only an option to choose whether you can have the sidebar on the left or right how could someone use both sidebars? what code would i need to add?

Hi.
Unfortunately, right now, this requires the addition of a new module position and large changes in CSS.
But probably soon when we change framework to new version, this same as we had in Meet Gavern template it would be much easier.
