Allow file types in MS CRM

Hi Experts, there is way to configure to BLOCK some file extensions in MS CRM.

can we just mention the extensions that I want to allow. I know (~Block) is allow.

but the difference is, if I want to allow, I may allow very few and know files and if there is any new files extension came in future and has to be blocked, I need to add that in the blocked list.

so I prefer to list those only that I want to allow.

any thoughts most welcome and thanks in advance.

Regards,
