Why not use your log book as a journal? Log everything that you fly....left seat, right seat, safety pilot sic, pic, x-country, night, ifr, approaches, etc...... but.... make sure that you keep seperate columns....And when you apply to an airline, ask the recruiting people for their definition of PIC, TOTAL TIME, TURBINE etc....every airline is different...and the HR department does not use the FAR's as a guide when they come up with their list of requirements. To some, pilot in command is defined as "captain time" and to others they use FAR 1/61. Also while you are checking with them about requirements, find out what the mean by a college degree. There is a large difference there as well. To some, you have to have physically attended a college and to others you can do it all through correspondence......and the place for these answers is not flight info . Go straight to the source, get the answers and plan accordingly.......
