I do not use WW for that so I cannot answer it in detail. But I'd start with reading the addon description and it links to the Wiki and FAQ section:
"Wiki and FAQ can be found on GITHUB"
https://github.com/nicokimmel/wizardswardrobe/wiki

If you do not find the answer there, you can raise a question to the dev here, or search if someone asked the same/similar already:

Maybe this helps, it's another user's comment about a similar question:

Re: Seperate pages for each trial

When I enter a trial the addon switches to the page for that particular trial and this stops my key binds from working. At each boss I need to open it and manually turn it back to the page I want to get them to work. I cannot see a toggle to disable this and get it to stay on a particular page.
Having a build for each boss of every instance would be great and is an awesome feature if I was min maxing and regularly doing hard modes but I am not.
I know there is a toggle to stop auto equip, but there doesn't appear to be one to stop auto page turning. This would mean that for every slight change I make to my builds I would need to save it for every trial or arena I may wish to enter individually just to get a simple key bind to work.
Have I missed something simple? I often do

Wambo:
There is a page for substitue setups: "sub" in legacy, under MISC in the new view
There you can set your boss and trash setup and it should load if you don't have setups saved in the zone you went to. Enable it in the settings for dungeons and overland




I've added your question there as comment, maybe someone will answer me there or here for you.
