Accessibility Issue in Arranging the Menu Items

Hello
I shall firstly thank WordPress team for their utmost attention to accessibility standards, which makes WordPress unique among all CMSs. All WordPress core features are fairly Accessible for me as a blind person who uses screen reader (JAWS), but I always have problems with rearranging the menu items. Although the menu-items are also very accessible for a blind person and I can re-arrange them very well, this process is very time consuming for me, because; for example, if I want to send a menu-item from position 16 to position 11, I have to press “Move Up” 5 times. The problem is:
I don’t have any combobox that assigns the mother-item and the item-position. Therefore, I have to adjust the positions by moving each item one by one, level by level.

Suppose I have a menu with lots of sub-menus and sub-items. Now, I want to add 6 new sub-items to the different menus. Of course, when I add them to the menu, they are at the end of menu. If I want to bring each item to a certain position near the center of menu, I have to click “Move up” and “Move down” one by one for many many times over and over. It takes me about 2 hours to rearrange those menu items. I hope I could explain clearly.

Solution:
Beside each menu item, there is a link called “Edit Menu Item”. When I click on the link, a set of options open up: move up, move down, name, etc. I would like to have two other options as well: mother-item, and position. For example, I adjust the mother-item of “Audio Translation” as “Translation”, and I adjust its position to “2”, which means subitem number 2 under “Translation”. I hope I could explain clearly what I mean. If I can adjust the menu positions with comboboxes, I will not have to click “move up” and “move down” many many times.
