Websockets permessage-deflate - Any way to compress once and send that to many clients?

I am currently facing the issue of occasionally needing to transfer a lot of data at once (>100kb) to thousands clients at once. I am already using Messagepack over JSON to minimize the size of the data sent over JSON, I am however unable to use Protobuf because only part of the data embedded (could have, doesnt have atm) a fixed format, so I tried to look into WS' permessage-deflate, but as far as I understand I would have to run the compression for every single client that I am trying to transmit the message to.Am I correct with that assumption or is there a way to compress once and send to multiple clients at once?Ty in advance
