automation problems. the first pass doesn\'t stick
 

hi im using pro tools 7 on an M box with a power Mac dual 1.25GB G4 with 1GB ram
when i go to start automation for a session it wont keep the first pass.
i used to start a session (in pro tools 6) by getting my main settings, level, eq, reverbs etc set then putting my channels into write mode. after i had written first pass it would set that to the end and i could jump in with write mode or touch mode and it would revert after to my original settings.
the only way i can make it keep those original settings and revert is to write in touch mode and move every single element (ie all different volumes on eq and panning etc etc) whilst playing so that it can reset its self. does anyone understand what i just said and can they offer me some sort of suggestions as to make a first pass like this is very time consuming and a right pain.
