Endgame map layout agency suggestion

Hi, I come with a suggestion to add more agency in the endgame.

First, I like very much the system of the atlas, the different points of interest like unique maps, citadels, corruption zones, etc. It adds variety to the gameplay by pathing through different map layouts and biomes, it feels good.
Tho, after a time, when I want to push the farming of certain mechanics or I'm just being bored of certain clunky layouts for my build, I would like to be able to choose which layout I run.

There is my suggestion, add maps with predefined layout like in poe 1, which you can run via the realmgate or whatever, something outside the atlas. This has for effect to give you the agency you want to do the content that you like and also balance it in the way that you don't progress in the atlas anymore, you don't get citadels, you don't get unique maps, etc.
Make them accessible only in the very endgame, t15 or so, as a sort of reward for completing the atlas, you can run what you want now and it has a cost.

This way, you can also add favourite maps or just make that the maps only drops their layout maps for sustain. People who like the atlas can continue running it and it will be more rewarding since less people will do it and it's becoming a farming strategy!

Hope you enjoy reading,
