[ASK]MTP for NOTE N7000

hi all master in this forum.

condition:
Samsung Galaxy Note N7000
ICS 4.0.4

I am an android user and nexus fans,
I use nexus s then currently use Galaxy Nexus

Actually a couple days ago my father just bought Note N7000.
I see something diffferent from my galaxy nexus.

Here is what i want to ask to all master in this forum.

In my Galaxy Nexus, whenever i open apps in setting menu. i find my phone merge the size of its disk. like currently usable disk space for my galaxy nexus is 13.3 Gb then i got about 13.3 Gb to install application or i called this from the internet is MTP

But when i open apps menu in my father i got downloaded and on SD Card. Actually this is same like nexus s.
What i want to ask is..

Can we merge the disk space because we know Galaxy Note has 16Gb. I mean make the disk management like Galaxy Nexus so i dont need to move the application that i install before to SD Card?

Sorry for long post.Thx very much
