Add account sender override option to multicall, useContractReads, readContracts

[BoilingSoup]

Ability to override the sender for multicall seems to be missing.
Viem's multicall has this option, but not wagmi's multicall, useContractReads, readContracts functions.

So this feature is missing?
I was trying to override msg.sender in useContractReads, but unable to do so.
I tried the following but nothing worked.

const earnedRewardsFunc = useContractReads({
    contracts: [{}]
    overrides: { from: account.address },
  });

const earnedRewardsFunc = useContractReads({
    contracts: [{}]
    overrides: { account: account.address },
  });
  
  const earnedRewardsFunc = useContractReads({
    contracts: [{}]
   account: account.address ,
  });

  const earnedRewardsFunc = useContractReads({
    contracts: [{}]
   from: account.address ,
  });

Thats the exact reason I want to override.
What if inside read function I am using msg.sender?

Do you know how multicall works? It's an external contract that calls the functions for you; you can't override that.

You can create your own function for calling multiple reads in your contract.

how does viem do this then?

I haven't tried but I assume it works similary to providing an account override to useContractRead.

msg.sender starts as the account you provide, but when it goes through the multicall contract msg.sender will become the multicall contract.

Yes, thats the issue I am facing. I think I need to loop useContractRead now 😪,
if wagmi uses viem under the hood (or anythinv idk) and viem has this feature. Wagmi should also atleast give what they are giving

I agree it should be consistent, but in both our cases the account override would not help. I'm fine with this being removed from viem.
