Stop primary domain showing in email link redirect

My customer is working with multiple brands.  Links from emails populate as the main domain when adding the tracking parameters and then redirect to the correct brand domain (happens over seconds). I am aware that this is expected behaviour and the main solutions are either changing the domain you use for link tracking before each email send (which is not scalable) or having separate portals.


With the introduction of brand partitioning is this something that we will explore?
