The other way to do it is by having a maintenance control organization that co-ordinates the defect with the crew. If the defect is in fact non-airworthy or even an MEL item, after reviewing it with MC, an MC Control order is issued and the crew defers it to the carry over list using that number This can be done via radio/landline/fax. The defect is closed on the log page but open in the B defect/carry over log. If the defect creates an AOG situation, then MC and consequently the airline are appraised of the situation and co-ordinated recovery action can quickly begin. The cabin logs can invariably carry open items unless they relate to emergency equipment in which case they get an MC control number or fixed.
