C4C - Assign marketing attributes default values on creation

In SAP OnPremise it was Always possible to assign the Marketing Attribute Default values automatically when creating the Account/Contact Person.

Is there a way to accomplish this in C4C? Via Workflow we also do not have the Option to set the Marketing Attributes unfortunately. And something like the 'Expert Tools' known from On Premise also seems to be missing.

Is there a possibility to do that currently in C4C?

Background is that we're trying to search for e.g. Contacts with values as 'Marketing Attribute does not equal A'.

But in this constellation all contacts do not Show up who do not have the Attribute Group assigned at all.

Many Thanks,

Kris
