SPP ACL for Networks or Subnets

Dear all,

is it possible to create ACLs under a SPP using IP networks/ranges instead of individual IP addresses?

We want to include some network ranges in a whitelist but it seems that network ranges are not possible to be included in ACLs.

Could you confirm us this or otherwise how to do it?

Let me know if further info is required.

Thanks,

Rafa.
