Limiting the Report Layout access other than Authorization Object S_ALV_LAYO

Question

Dear Experts,
We have an issue of Layout Access limit to Users coz unwittingly these are being deleted.
(Example: IW39 à after F8 à Settings à Layout.)
The Authorization object S_ALV_LAYO which limits the access, has been defined in the multiple Roles, where every User been assigned with these Roles across Three Continents.
Instead of hampering the existing Streamlined Roles, looking for other Options since if it may give odd behaviour after modifying the Roles then all the Users across the continents will be effected.
It will be grateful if we get other options to limit the Layout access instead of controlling through Authorization Object.
Thank you & Have a Great Day!

Answer 1

Thank you Sebastian & Terence,
The Global Roles has maintained with Authorization Object (S_LAYO_ALV) and these are been assigned to Every User coz all Users should access these reports.
So now every User has maintained with the Authorization Object to access.
Now we are trying to Control the Access to limited Users through without hampering the well maintained/streamlined  Roles, since if any adverse effects on the modified roles may impact to all the Users across the continents.
Looking for other options.
Thanks, I appreciate your time and efforts on this.
