If you’re specifically referring to the use of Shopify Payments here, I have confirmed with our Payments team that it would not be possible to split the payout into more than one account due to how the gateway functions.
What I can do for you from here is to file a request for this functionality to be added to the platform in the future.
If you can share a little info about why this is important to your business, this will help us file the most accurate request with our developer team so they understand why this is important to our merchants.
I look forward to working on this further with you!
