How to remove a LCB contact from dialer

I dont want to call any more LCB's for a specific property once it is sold, so we have to remove them from the power dialer. This is how you do it:

You find the LCB contacts by searching for the tag by the name of the street number & first part of the street name > then you select those contacts > and remove the contact TAG called 'dod dialer' : then those contacts are removed from the power dialer workflows.
