Inverse filtering across tables, possible?

Hi all, 

I am fairly new to Power Bi. I have searched the internet, but I cannot seem to tell if this is even possible through power bi - here goes..

I am trying to map out which emlpoyee id's are missing certain trainings and who has already acquired certain trainings. I have 3 tables: number 1 is with employee information (Id's, name, title etc.), number 2 is the list of training that has been acquired by employees based on id's and number 3 is the unique list of trainings available. 

Now, it is straight forward to get the list of employees and training already acquried (as it exists in table number 2), but how do i get the opposite (all the uid's that have not concluded certain trainings)? 

Do i need some kind of inverse filtering? 

The ultimate goal is simply to have two dynamic tables: one that lists the people who have acquried training and one that list people who have not acquired training. Both have to filter when I choose a specific training in a visial or the like. 

I hope it makes sense, otherwise let me know!

Ps. I realize that this might already have been covered in a previous post, however, I have still not been able to solve my issue.
