API endpoint to get attestation duties metrics for withdrawal address does not return total sync signature

Helloooo team

I am currently trying to use rated API to query Get validator attestation duties metrics. I am interested in understanding the missing sync signature. If I query the endpoint GET/eth/entities/{entity_id}/attestations it returns the 'sumMissedSyncSignatures' but it does not provide the total sync signatures.

I can get 'sync_signature_count' through the endpoint GET/eth/validators/attestations. However in order to query multiple validator indices together, I have to add multiple query parameters as shown in the picture. Since I have 3k+ validators, it can be a bit tricky to send such a huge query.

TLDR: It would be great if we can add sync_signature_count for the endpoint GET/eth/entities/{entity_id}/attestations
