Get-PnPUserProfileProperty "-All" flag?

[MisterZedd]

Hi all,

I've found myself needing to get all SharePoint user profiles missing from import, and I keep being referred to try doing
Get-PnPUserProfileProperty -All | Where-Object ($_.Account -like "*-DELETED-*")

From everything I'm finding, this doesn't appear to be a real flag... Am I incorrect in this assumption?
If it's not, is it possible for it to be added? Our tenant still uses PowerShell 5.1, so I'm using module v1.12.0.

Thanks,
