Attestation removal of customized attestation policies and attestation procedures.

Hi all,

I have a question related with the attestation removal. In my project, we have many attestation policies with customized attestation procedure. When the attestation is denied, the requested entitlements should be aborted. I found that the "Abort" method of PWO is not available in version 8, which means I can not use customized script to do the removal. Then I try to use the OOTB removal function, it requires the related default attestation procedures. However, our attestation procedures are mostly customized.

Now I have no idea how to do the attestation removal. Does anyone have an idea how to remove the requested entitlements after attestation was denied?
