It would be nice to have the same option to keep objects out of the AD CS in AAD Connect as MIM Sync does. We have over 300K groups and quite a few very large security groups with 50K-250K direct members. We would like to be more granular on which groups even make it to the AD CS to be processed. Right now we only need to flow 20-30 security groups. The current delta sync cycle takes from 45min-5 hours to complete. This needs to be improved.
