Ledger Starter PIN Options

Hello,

I'm moving from GreenAddress and hope to use the default Ledgerwallet app and mycelium.

I was excited to learn that I could download and implement my own starter usb stick. My only concern is that in the tutorial it shows and asks for the user to set a 4 digit pin, I was using a much longer one on GA. I'm just wondering if it is possible to set a longer PIN using the starter usb ISO.

Edit: I'm using a hw.1, forgot to put that in original post.
