Sending as Multiple Companies/Brands

Sending as Multiple Companies/Brands

We currently use Zoho CRM. We have multiple companies/brands that we operate as, and identify each Contact and Company with a Custom Field based on the company/brand.

We are considering using Zoho Campaigns (replacing Mailchimp).

I know I will be able to segment Contacts based on this field to ensure that they receive the right branded campaigns, but it seems we can only add 1 set of Company details in the settings of Zoho Campaigns. So although the email may be branded correctly, the Company details in the footer will not be correct.

Is there any way of adding multiple companies into Zoho Campaigns so that all sender details are correct for each brand?
