Delegation without snapshot participation

Hi, I have purchased some ADA earlier last year and left them in the Atomic wallet since. By reading about staking and delegation lately, I understand that only people with ADA in the Daedalus or Yoroi wallet was participating in the snapshot. Please correct me if I am wrong.
Is there a way for me to transfer my ADA to the Yoroi or Daedalus wallet now and still be able to delegate?
Thank you.

Sorry, no staking for people in your position until mainnet.
