Thread:Project:Support desk/Having full numbering path in titles

Hello,

I have been looking into this for hours with no luck. How can I create a list with full numbering path? For example, now I have a list like this,

1. First 1. Third 2. Forth 2. Second

But I'd like to have it as follows,

1. First 1.1. Third 1.2. Fourth 2. Second

Thanks for your time,

Best,
