Changing the role at approval level in CUP

Hi,

Is there any possibility to change the role at approval level instead of going with selected role in CUP request?

I will explain the scenario of the above mentioned query. End user raised a CUP request for assigning a role to get some transaction access and he has selected a role while raising a request. But that selected roles is not a right one. So as an approver, we need to change a selected role.

Please advice in this.

Thanks & Regards,
