Save Quarterly Update

PUT /tenants/{tenant}/clients/{client}/mtd/quarterly-updates

Saves the cumulative year-to-date figures for one income source, creating the draft on first save and replacing the figures on later saves. Editing figures that have already been sent starts a correction: the record returns to draft and the previous declaration is cleared. Nothing is sent to HMRC by this call.
