Wierd Mangle in IP/Firewall!

Hey dear Mikrotik Masters,

I have more than 40 of Mikrotik devices. Most of them is RB2011 (RB2011UiAS-2HnD).
Recently I update some of my routers to ROS 7. In version 6.49 I was able to create a Mangle in IP/Firewall/Mangle and Mark routing as action with custom name in “New Routing Mark” box. But in version 7 there is only one “main” mark and it isn’t editable.
How can i able to make it customize?

Kind regards,
Mori

Add a new mark using Routing Tables and a new FIB if required.

Then this table will be available in Firewall.
