workcenters-3 levels

Hi everyone,

I am customizing workcenters and I am wondering if it is possible to have 3 levels.

Picture will explain better than words:

Here I have Sales Cycle with a sub menu Sales Planning that will then lead to another menu with links Campaigns, Leads, Opportunities,etc...

Is it possible to create those levels? I have only found how to create Sales Cycle > Sales Planning.

Thanks a lot,

Regards,

Anaïs
