[SDF-92587] Red envelope - mark manually as read

Hi there, 

is it possible to mark ticket answers as read, to get rid of the red envelope?

Problem: 
From SDP, we are "talking" to other ticket systems which belong to different service providers.  
So we really often get automated messages from these systems, with status updates we do not have to respond. 

Actually we have to track so many tickets, that an effective overview is no longer possible with SDP.
