Does Nicepage have Sidebars as Themler have?

Hi.

Does Nicepage have Sidebars as Themler have? I mean areas that you can assign to specific templates and page. For example: if I need one block on all pages, I don't need to copy it on each page manually, but just add to Sidebar (as with Header and Footer).

Here is example from Themler
