Hello there, jarpac,
It would be good to be able to have this option. Adding bank details on the memo is currently unavailable. For now, you can only do it manually.
I'll send this feedback to our product developers. Please know your voice is important to us, and we take customer’s suggestion as an opportunity to guide us on which area of the product we need to improve on.
Let me know if you have other things in mind so I can list it up.
