[tpm2] Hash sequence duplication without ContextSave/ContextLoad

Hello,
 
I need to duplicate a hash sequence. This is to implement TPM-based version of OpenSSL's EVP_MD_CTX_dup.
 
Background: EVP_MD_CTX_dup can be used to duplicate the message digest state. This is useful [...] if large amounts of data are to be hashed which only differ in the last few bytes.
 
 
So far I am using ContextSave/ContextLoad, but Windows is blocking these TPM commands.

Is there some other way to duplicate a TPM hash sequence, please?
