Nope. Just gotta go with it. It reminds me of the time at 11pm when I was doing the final change before bedtime, inbetween boobs (as it were) that DD2 pooed FIVE times. Each time after I had put the new nappy on. I just had to laugh really.
It's part of the "joy" (!!) of newborn babies - it will soon settle down, don't you worry.
Oh - I would just add a couple of things, because I don't think I was being helpful.
Take that babygro as far back as possible, and stick a muslin / terry square under her bottom before you take off the nappy and whilst you are cleaning up. At least this way, you can just catch the wee/poo to hopefully avoid the change of clothes.
Unless she is pooey - don't bother changing in the middle of the night. Those nappies hold a huge amount of wee - and when they are sleeping through, you wouldn't change in the night anyway, unless you had to. It won't do her any harm.
Even though we use disposables, I always changed ds1 on a cloth nappy, and then loosely wrapped it around his nether regions to catch any "mid change" toilet activity. I'd leave him loosely wrapped for a minute or so to get on with whatever he needed to do. If he did something I'd do a second (or even more) loose wrap till he'd got it all out. Saved a fortune on disposables. Also meant that anything coming out did not get on his clothes, but rather on the cloth nappy, so a change of clothes was not necessary. Made changing take a bit longer, but mostly meant that once we got the disposable on, we didn't have to worry about a change in a few minutes time.
He grew out of it in a few weeks though.
The upside is that you know that your baby's system is working well!
We have the same thing - dd often goes for the hat trick and manages to posset, poo and wee mid change . We use 2 sheets of kitchen roll under her bottom, which seems to catch the poo before it sinks into the towel we have over the mat - of course is of no use for wee, but having a roll of kitchen roll to hand means soaking up the wee is quicker.
