Allow Users to Edit Ranges.

Hi everyone,
I want to allow users to edit some ranges after protecting and sharing the work book. In the sample file which i have attached whatever the cell highlighted background with light violet color should be allowed for the users to edit and only some specific people in my work group.

In this file i have just given 2 ranges (Bay 1 & 2) where as in my original file i have around 11 ranges (Bay 1 to 11) each with 50 rows.

The pre defined option for this feature is having some limitation which i couldnt utilize it in this sheet.

Someone please help me....
