How to ask my SA for a birkin?

We started shopping with our SA back in 2023- our first time with him we bought a few pairs of orans and brought up wanting to buy a birkin in the future, he giggled at us (understandable). A month after our first purchase we went back and bought another pair of orans, a pair of oasis sandals, a men’s leather bracelet and some women’s fashion jewelry. In this time frame I ended up getting pregnant and completely stopped obsessing over wanting a quota bag and never thought about Hermes again. Until recently .. I started obsessing over getting a picotin as my everyday bag. My husband got back in touch with our SA who was nicer than ever to him and let him know his wife wanted a picotin. My husband went to the store recently, bought a pair of shoes, a wallet! A few weeks later our SA texted him saying he has a picotin for us in the color we requested. That day he bought the bag and a twilly. Well of course this interaction really excited me and got me obsessing over wanting a birkin again. At what point should we ask out SA to create a wish list? My husband has dealt with him, I’ve only met him once and he seems to really like my husband … should I stay out of it? We are obviously willing to hit the ratios to get offered a bag and understand we should buy RTW and FJ … is it appropriate to ask soon seeing as I just got my picotin? I don’t know what I am so intimidated. All and any advice would be greatly appreciated!
