Change Bengali Keyboard Format

[Corvas]

Type-1 (Recent Keyboard Format)

Type-2 (My Preferred Keyboard Format)

Actually I am not good at typing Bangali on this type of keyboard (Type-1), So can I access (Type-2) type keyboard with default inbuilt keyboard function.

As I don't prefer any third party Keyboard apps. So how can I do this. Can you please suggest me.
