tailwheel solo before ppl

hey guys, have a quick question. If i do flight training in my own aircraft, lets say its a tail dragger, is it possible to get my tail wheel endorsement before i get my full ppl, or by soloing in my aircraft do i already get my tail dragger endorsement, then i would have to go get my sel rating right? what im trying to ask is can i solo in my tail dragger (most likely a sonerai 2) and get my tail dragger endorsment before i get my ppl. and then after i get my ppl i would have to get a normal sel rating right? or do i have to get my sel first and waste a bunch of time and money training in someone elses aircraft. and after that spend even more to fly my own. please help, i confused my self writing this so if your confused dont worry ahaha
