How to tell tell Studio Pro 2017 SR1 to ignore certain strings of characters in the source, so that these get ignored in project calculation? Or perhaps even better - also make these separate segments in the project and have them locked?

Hi Team,

I was wondering if anyone could perhaps shine a little of their selfless wisdom on this. 

There's this client with an IT system that generates their source content for translation in excel. There is customer tagging peppered in there, or "technical text" but not HTML or any other formal markings, just strings of characters that are important to that particular custom IT system. These can be identified by certain common features. 

These strings oughtn't be translated but must be transferred into the output exactly as they are, down to every single character. 

Is there an obvious trick we're missing to easily tell Studio to do just that? I mean identify these upon an algorithm, bring them over into the translation as separate segments and and lock them up? 

Many thanks indeed!

Best regards,

Adam
