There's no given, normal way to edit your PL (e.g. a default console command) in ESF. If you want PL quickly, add powerful bots or collect the Dragonballs.
There's third-party plugins for a serverside mod called AMXX Mod that allow you to do what you wish, but the key word there is third-party. They're not created by the ESF team, nor are they supported here. Look into that if you have experience running a server and want to give it a try, otherwise just stick to the normal way of playing ESF.
