I have a workaround solution for this, here goes:
Follow these steps in your joomla site Admin panel:
1. Go to the module manager, open the desired module and give a unique name in the position field. If you want to use it also at other common position such as left or right, then first create a copy of this module and then for the new copy, create a unique position name. Example: custom1.
2. Create a new article preferably uncategorized. Give it the name of your module.
3. In the body area of the article type {loadposition custom1} and save your article.
3. Create a Menu link to this article in the desired menu. You should select 'Article layout.'
Thats all, your module will now load from the menu link directly.
This has an added advantage of giving you SEO prominance based on the meta info you give for this article.
You can check my EMI Calculator module by clicking the link on the topmenu of my site:
