Multiple Values for Overview attributes

Hello Zammad Team,

We need to be able to add multiple values to an overview conditions attribute or to be able to add additional conditions for that attribute.

For instance, for version 2.6.x, I can add a condition with the following:

Customer | is not | specific user | ‘User A’

I need the functionality to add an additional user to the user field OR to add an additional condition to exclude another user. Example:

Customer | is not | specific user | ‘User A’
AND
Customer | is not | specific user | ‘User A’

OR

Customer | is not | specific user | ‘User A; User B’

As it currently stands, I can only add one condition for each attribute and can only add one value in the field.

There is already a Feature Request on github.
