ZFP - Request to enable sheet view in all kinds of layout

Doctors often open 2-3 comparison studies and intend to observe the progress of the lesion in ZFP. However, it is unable to use Sheet View function when opened viewports are more than 3.

Currently the "Sheet View Layout" button works only on 1x1, 1x2 and 2x1. When other than this kind of layout, the button is greyed out.

Then they requested the "Sheet view" function is enabled on even if it was displayed more than 3 division layouts (For example, 2x2, 3x2 and so on).
