How to manually move between landscape and portrait pages?

Hi all!

I need to (as an author) set orientation of page manually depending on element. 
It is required so that I can have large images/tables on Landscape pages,
I have created two page sets. One for Portrait and other for Landscape.

I am currently using outputclass=landscape or Portrait to start new pages on elements like concept and Task.

Now this works but in order to add these conditions to these elements, I have converted the elements from Unstyled (default) to Division 2-4. This causes an issue in my header which is supposed to display only header level 1 or division 2 using Division Reference.

However, it displays the first task/concept element irrespective of the division level. Note that this issue only occurs for the unstyled elements that are now Division style. 
Either Concept/Task is not being converted/recognized correctly, 
or I converted them incorrectly or the system is broken.
Any suggestions?
How do you achieve this?

In DITA, unstyled elements inherit the style of the element they are specialized from, i.e. unstyled <concept> gets styled by the style for <topic>.

 

In this case, you should be able to apply your styling to <topic> and have it format the things that inherit from topic (task, reference, concept). Try reverting the styles you've applied to <concept> and <task> back to unstyled, and add your pageset conditions to <topic> and see if that gives better results.
