Sending tokens to Whitelist people

Someone would know how to answer me, I'm thinking about creating a token and making a pre sale using a private whitelist, I'll give away some people, another pre sale would be on dxsale or pinksale, but how would I do in the future to distribute the tokens to all the people who acquire by private whitelist? how would this distribution be? I would have to send wallet by wallet or is there a method for this sending to happen as agility, another question would be the following is it possible for me to send these tokens to people together when the liquidity is signed by dxsale or pinksale? because if I send as coins from the private whitelist I would have problems, and if I send as coins after the liquidity is Added too. Is there any method then for these tokens to be sent at the same time as the liquidity is sent?
