Deposit with metadata

I see there is possibility to withdraw a token with metadata from matic chain: pos-portal/ChildMintableERC721.sol at d06271188412a91ab9e4bdea4bbbfeb6cb9d7669 · maticnetwork/pos-portal · GitHub

But I can’t find similar possibility for deposit with metadata: depositData seems to be hardly locked to be an array of token ids. pos-portal/RootChainManager.sol at d06271188412a91ab9e4bdea4bbbfeb6cb9d7669 · maticnetwork/pos-portal · GitHub

Is there any possibilities to deposit tokens with metadata?

Can you point out the place in code where it can happen?
