Replace a user ( authorization tab)

Dear Experts,

Does anyone if there is a function/report to change in a massive way the authorizations for replacing one user by another? ( Bucket, portfolio item, project scheduling....)

I know that you can configure a substitute, but this is not enough for us, we need replace him in all the objects that the user is assigned.

I have checked that technically shouldn't is very easy develop the report but I would like to confirm that there is nothing standard.

Any idea?

Thanks!!!
