ethers Get logs at specific blocks

Question

I'm trying to get logs on ethers however, right now I'm chunking out the blocks based on the max blocks my provider allows (3500). However this is inefficient and slow, (Note: yes I know the graph probably would be better)

let fromBlock = parseInt(filter.fromBlock as any) ?? 0
let toBlock = parseInt((filter.toBlock ?? blockNumber) as any)
let blockSpan = toBlock - fromBlock;
const numberOfChunks = Math.ceil(blockSpan / MAX_BLOCKS_PER_LOG);

var logPromises = Array.apply(0, Array(numberOfChunks)).map((_,i) => {
  const fb = fromBlock + (i * MAX_BLOCKS_PER_LOG)
  //Logs filter is inclusive so we need to subtract 1
  const tb = Math.min(toBlock, fb + MAX_BLOCKS_PER_LOG - 1)
  return provider.getLogs({
    ...filter,
    fromBlock: fb,
    toBlock: tb,
  })
});
//...

I would like to lets say I would like to getLogs as block [315536, 355536, 392301], I know I can make requests to get logs for each individual block, however I would like to make a single query, so I don't have to make that many additional requests to the rpc provider.

Is this possible?
