Multiboard information about my variables

[NeosDany]

Ok, I'm creating my custom hero map, and I need to show the skill level the player has in his multiboard, which currently shows played time in top of it and next wave just below, now the thing is, I'm currently storing when a player learns an ability or levels it up (because this is done in a shop rather than in the hero), in a PlayerSkillInteger[PlayerNumber], and now I'm asking here for advice in order to make an efficient trigger in order to implement this information, about what the player has, because you can unlearn an learn anything else, I hope you understand my idea.
Thanks in advance
