There are different techniques for anger mangement. I think there's a lot of value in talking things out long term and gradually gaining a greater self-understanding and more inner peace, but I went into therapy because I was having explosions at my daughter due to a number of reasons, and I demanded, after a while, some practical techniques to help me hold my temper and make other gains while I managed the other, deeper work. So yes, I would challenge yourself and your therapist to make the progress you want. Set yourself up for success with some practical tools- for example, someone here I think it was, suggested a box, I forget what it was called, maybe a coping box, and I used that idea to great effect- I found a small box, decorated it and put a baby picture of my daughter in it to remind me of her at her most vulnerable so I wouldn't yell at her, and I put other soothing things in it to help cool my temper, like a soft bit of cloth, something with a soothing scent, etc.. When I felt myself getting upset, I'd go to the box.
It was no magical cure all, but it helped me do better while I worked to get better.
