KYC/KYB for multiple accounts – still a headache with some brokers?

Running into the usual hurdles with KYB when setting up multiple corporate trading accounts with different entities, even within the same umbrella organization. It's frustrating when the process isn't streamlined at all, demanding a full re-upload of every document, often for the same beneficial owner. Are others still experiencing this level of inefficiency, or have I just been unlucky with the particular brokers lately?
