The customer name needs to be included in the Disassociation Email. Including the claim number only means that you have to click into Partner Center to see what was disassociated and completely removes any hope of searching your email box for what has happened with a particular customer. And since the disassociations don't get written into the notes of the claim, the email is the only way to follow what has happened with the individual workloads.
Status details
2021-08-11 - Data & Tools Team - This has been submitted to Partner Center engineering, no ETA at this time.2021-07-07 - Data & Tools Team - this is still on the radar and we are tracking it.
2021-03-29 - Data & Tools Team - seems like a reasonable ask. Working with CPOR team to see if we can get this added
2021-03-17 - Assignment Team - assigning to Referrals Team to triage.

I just copy and paste the tenant ID that is sent via mail to FTOP FRP View dashboard and search which customer is disassociated. But still getting a name on e-mail would be more efficient.
