The PPL course (JAR-FCL 45 hours minimum) must include:
10 hours supervised solo time - No problem, you already have a column for this.
25 hours dual flight instruction - similarly you already have a column for this.
2 hours stall awareness and spin avoidance training - so mark one of the spare columns " SSAT " and enter the time that you spend on this which will be less than the total time of that particular lesson.
5 hours solo cross-country time - so mark one of the spare columns "Solo XC".
This will make checking you have all the correct minimums easier both for you during the course, and for the CAA when you send off for your licence.
But, as has been pointed out, how you fill in your logbook is entirely up to you, subject just to the minimum information required by the regs.
Good luck with the course !
