Turn off Intercompany Adjustments?

Hi There

is there a way to turn off the intercompany adjustments feature?

I can get rid of it from the menus.

However, I don't want this to be an option under the period close checklist:

The reasoning for this being that, because of it's limitations we are using a custom solution in place of it:

Namely, creation of invoices and vendor bills to on charge for expense claims paid by one subsidiary, though relating to a project in another.

I don't want users to accidentally generate and post intercompany adjustment journals for this using the period close checklist.

Thanks
