If you add model elements in the callout, it will add them to the project, in all views where it will be visible.  You can add detail items to the callout without affecting any other drawings.

its not like add element it like change size of grid without size without changing it on plan you know what i mean.

It has to be a 2D view specific change; otherwise, any changes to 3D element or elements with 3D extents will be reflected on other views too. Datums (levels and grids) are 3 D elements... hence you cannot resize a grid from 4x4 to 3x6 without it being reflected on other views. Unless you hide the original grids and add a 2D detail item grids

What "grid size" and what are the "extra stuff"?

If these changes are alternate designs, have you considered using design options?
