Yes! The creator of the trust is able to take any asset out of the trust or put any asset into the trust. For example, if the creator of a trust had opened up a savings account at a bank and had titled the account in the name of the trust, the creator may still, at any future date, during his or her lifetime, completely close that account or take any amount of funds from that trust account and may instead invest them in stock, bonds, or mutual funds which are titled in any other name. The creator of the trust has absolute control to determine how title to assets is held, or whether assets are in or out of the trust.
