I do not believe that there is any entry in the file system for current ACL. There are a couple of options that you an consider:
- you might scp the new ACL as a file in the filesystem and at the appropriate time copy <file> running-config
- you might take a current copy of running-config, edit it to insert the new ACL, scp the updated config to router startup-config, and at appropriate time copy startup-config running-config.
