Unable to pass initializer arguments when using proposeUpgrade

I'm using defender and hardhat for my project that uses a Transparent proxy.

Currently, our multisig is the owner of our proxy therefore, a proposal must be made before upgrading the implementation contract.

When creating a proposal, I do not see an option to pass initializer arguments.

Here is my hardhat task :

task("propose-multisig-upgrade", "Propose a new updated contract to be upgraded via multisig")
  .addParam("proxy", "Address of the proxy")
  .addParam("name", "Name of the updated implementation contract (must be existant in artifacts)")
  .setAction(async (taskArgs, hre) => {
    try {
      const NewImplementation = await hre.ethers.getContractFactory(taskArgs.name);
      console.log("Preparing proposal...");
      const proposal = await hre.defender.proposeUpgrade(taskArgs.proxy, NewImplementation);
      console.log("Upgrade proposal created at:", proposal.url);
      return proposal.url;
    } catch (error) {
      console.log(error);
    }
  });

Is there a work around for this?

PS : I do not want to deploy the implementation before hand manually then propose the upgrade.

Thank you in advance.
