Transfers to multiple teams cannot be made at once. With each transfer, the entire amount earned on P.A must be moved; no partial transfer amounts are allowed. The only way to transfer to multiple teams is to raise another block under your Personal Account and pick a different team to give to the next time.
For instance, if you earn $100 and transfer it to one team and then earn another $100 subsequently, you can issue a new transfer to a different team of your choice. To learn how to transfer funds, click here.
