MAME32 vertical and horizontal

[Gradius]

I use MAME32 and I've thought it would be a good idea to have to shortcuts, one for vertical games and one for horizontal games. So as to achieve this I've created a mame32ui-v.ini and a mame32ui-h.ini, each of them configured in orientation, vertical and horizontal. I've written a batch file that copies each file to mame32ui.ini and then load MAME. It works and I also like the fact that this way the list view and arrangement of games is fixed and appears always the same. I use a similar batch to delete all the .cfg and restore default.cfg. The problem with this idea with mame32ui.ini is that when you update the list of games when you add or remove a game, the list is never updated then next time you load MAME. Therefore, I would have to create both inis again anytime I update. Do you know any other way to do this that doesn't imply this problem.
