Yes but unfortunately and strangely Trust Wallet doesn't allow to import single adresses(only seeds) for Bitcoin, and BTC-like coins such as Dogecoin while it is allowing it for several others like Ethereum, Tron, BNB, Stellar, Gnosis, etc, so I guess this is why nobody proposed it here before.
You probably meant to say single private keys, right?
If you think about it, it's not really needed and could cause confusion for newbies and those who don't understand the difference between a private key and a seed. Eventually, it would mean more work for their customer support responding to questions from users about why their bitcoin is missing, etc.
Assets like ethereum and tron are account-based. You use one account/address for all your transactions. That's where your native coin is located and all the tokens on the network. Importing the seed for such an address or a single private key leads to the recovery of the whole wallet.
As we know, a bitcoin wallet can have hundreds and thousands of used addresses. Importing only one private key leads to a partial recover of a part of your total balance or none at all (if it was previously emptied). You need the seed to recover and gain access to everything. Single-key imports should be allowed, but I understand why it isn't.
