TPM2.1.0 on T61

[Frankenstien]

I have discovered (too late) that once you delete an entry in TPM2, you are not prompted again to re-create the entry for a given domain.
To my disbelief, there is no manual(ly) create entry, undelete entry or re-create entry provisions in this s/w (that I can find).
My online searches to date have not given me much hope for optimism.
Can anyone suggest a method by which I can trigger the TPM save entry prompt?
Thanks, FFF
