Concatenate Supporting Details and Account Alias

Concatenate Supporting Details and Account Alias into the same cell

Content (please ensure you mask any confidential information):

I'm looking to concatenate Supporting Details and the Account Alias into the same cell so that a user can quickly identify exactly which set of Supporting detail rows correspond with which Account. I've tried doing this a few different ways but haven't been able to make it work. One approach I was optimistic about was adding a hidden row where I don't display the supporting details and pulling the Account Alias from that, however when designating Member Alias to that row it will only pull in the first value.
