Hi @rois33

I am not sure but maybe check this app, and contact the developer to see if it can help in your case.

It says you can connect customers by tags or product purchases. Also, check the Mechanic app

https://apps.shopify.com/mechanic?ref=lightward&utm_source=mechanic&utm_campaign=task-library

It gives a lot of automation for different tasks, for example, this

https://tasks.mechanic.dev/auto-tag-customers-upon-product-purchase

auto-tag customers when they purchase a matching product.

Not sure if this is exactly what you need but you can test and see if it covers your workflow.
