Does the Dub Shopify app support tracking **lead** events (customer signups) independently of sales?

[Vigneshreddy625]

Is it possible to track only leads from Shopify using the Dub app?
For example, a user clicks a Dub short link, lands on a Shopify
store, and creates an account — but doesn't buy anything. Can that
signup be attributed back to the link as a lead, on its own, without
a purchase happening? The docs and the app seem focused on sales
attribution, so I wasn't sure whether leads are supported here. If
they aren't today, is it something planned?
