UWL substitution at workitem level

Hi,

I've gone through threads like [this|Substitute - Delegation in MSS;.

I've also read How-To docs related to Substitution Proflle. What I understand is that the Substitution Profile approach is task specific. So if you change it at the task level it applies to all the steps/ workflows where that task is used.

And this is what I don't want to achieve. e.g. I'm using SAP standard approval task TS17900100 in different workflows and at different levels of authorizations. I want the task classification to apply to a specific step of a specific workflow.

Any suggestions/ tricks/ workarounds/ pointers?

Thanks in advance.

Best Regards,
