Snip from recorded sessions

It would very useful if we could snip a process from a section within a recorded session. There is the often to select the snip icon but it says 'Must select a discovery to activate snipping'.

1 - why have the icon there at all if you cant use it?

2 - having the option to snip from these recorded sessions would add lots of value as often discoveries do not return full processes so you need to refer to the full recorded session
