Notify entries are stored in your "mirc.ini" file (editbox command: //echo -a $mircini) at "[notify]". Note that you have to close mIRC prior to any manual editing of the file. You could also create a simple mIRC batch script according to your needs (add only new entries from file / replace all entries with file content / save all entries to file / ...).
