CRM and KPI registry linked to HikaShop users

I want to develop a simple KPI registry for each client so that when they contact me I can store somewhere related to their user ID

Reason for contact, solution provided, no sale generated as a result of contact, sale generated as a result... etc, just a plethora of fields to follow activity.
I want to make as many registers as contacts each client does

Then I would like to have some way to export to excel or something for graph chart analysis

IS THIS already provided in HikaShop? (think not).

So if not, is there an easy way to create a new table that keeps as many registers connected to a client as needed with possiblity to create custom fields?
