Make a LinkedIn bot

I have some LinkedIn accounts and I would like to see all the conversations in one screen, without having to log into each account to answer every message. Then, when I answer the message using this interface, the message will be sent to the user from the right account.

I have a few ideas on how to do so but I will need your help, as the design should be great. I was thinking about something like Whatsapp and the ability to tag the conversations.
