user4346: With cardano-wallet or cardano-cli I can combine transactions (= a transaction with more than two outputs).
Is something similar possible with wallets like Yoroi, Daedalus etc.?
Example
I want to send 20 ADA to address1 and 30 ADA to address2 from my wallet in one transaction.

user4302: Short Answer: No
Long Answer: Pretty sure no, at least not yet.
In the technical flow section, there is a note explicitly stating that it is not possible.
