How we revise multiple security rows at a same time

Hi Team,

We got an request for a BA where they have given us 1200 roles for which currently Action security is applied for P0006 application where Add button is disable as it has a "N" value.

I want to modify all the 1200 roles action security  at a same time instead of selecting one record at a time and revising the Action security one by one.

I do not have a back end access, need a solution from JDE side using P00950 application or any UBE available in JDE which I can use to modify multiple security records at a same time.
