Setting Validity for a role

Hello,

We can assign a role to multiple users.

Is it possible to set a validity date for this assignment, so that the authorizations through this role are available till a specific date only.

I know it is possible to do so in SU01, but if there are multiple users to a role, it will be cumbersome to set the validity date for each user. I tried SU10 also, but without any success.

Please help.

Thanks in advance.
