is msol / 365 get license activation date possible?

Hi

I have been tasked with finding office 365 license activations.  All our users have theOffice 365 Education for students but only a handful have activated theOffice 365 Education Plus for students.  Students can optionally add this so i have been asked to find out when students have activated their plus subscriptions but when doing the following commands:

get-msoluser -UserPrincipalName username@domain | Select *

or

get-rsmailbox <username> | select *

I cant see a date stamp for activations for the Education Plus license.

Id expect to be able to list all the attributes of  user using the * wildcard so im assuming its not recorderd but thought id ask how other people achieve this or if its even possible?

thank You
