Multi-query parameter campaign integration configuration using the same assets

Hi,

We have a campaign that has a single landing page & form with different query parameters for distinguishing the channel.
We want to divide the same landing page content into multiple queries and link the conversion of each form submission to different Salesforce campaigns using response rule.
I basically understand it is necessary to create a campaign canvas for each query when splitting CRM campaign IDs,

In this case, we see a landing page step on canvas saying that "Use any following URLs when linking to this page".

My question is…

When distinguishing conversions of the same landing page linked to a campaign canvas (CRM campaign ID), is it necessary to assign an elqCampaignID when publishing the landing page for each channel? e.g. when publishing this LP for ad campaign (No inflow via email)
