How to track the sequence of visits of each specific person on the site, taking into account the source of the 1st entry?

Question

Google Analytics

Greetings. I honestly looked at a lot of materials on the topic of the question, but did not find the exact answer.
I test different sources of traffic to the site, for example, YAN and KMS, etc. traffic there is less "hot" than in organic search or context, I would like to track the customer's life cycle.
For example:
The first time on May 10, I went to the site through YAN, without making a purchase, left.
Then on May 12, the same person found the site already in the organic search and left a request.
May 15 - the client moved from the social network or entered the site URL manually and made a purchase.
Гугл Аналитикс дает такую возможность, особенно было бы хорошо смотреть не по каждому человеку отдельно, а целыми пулами трафика. Например нужно посмотреть, возвращаются ли люди первый раз перешедшие с КМС и какие конверсионные действия они совершают.
Спасибо, откликнувшимся!

we did this through a JS script that sends information about the source of the client's visit and his Google Analytics ClientID to CRM
