Default AOSP Roms - Saving Contact to SIM

I had asked this about TW roms, and was helped, thanks.

I've been on AOSP roms (for good) for a little while now, and now can't figure out how to do this, d'oh.

If I have NO google accounts created, when I try creating a new contact, it says that the account will be "saved locally". If the phone has a linked google account, however, it says it will be synced with that - gives me no option to save locally/to SIM card.

Is it possible, even? If so, how?
