No. Hash functions are specifically designed to make any shortcuts impossible. Essentially, they consist of many steps of scrambling the input bits, each step taking as its input the output of the previous one. If any such shortcut would be found, it would be considered a vulnerability, and the use of SHA256 for anything involving cryptography would be strongly discouraged.
