Close AP posting before GL and AR

Is there any way or has it been brought up to have a way to Close AP posting prior to closing the GL JNLs and AR? It would be very helpful to stop posting to AP especially prior to AR when you need to pull all the expenses for a month to bill out grant funding only to find out the following month that something was posted after the grant invoice was created. I know another software I have used has three buttons for closing, AP AR JNL where you set them each when you want them to stop having entries posted.
