Hi Cristina, this would be similar as in MultiTerm (if you are familiar with it) - you can freely define the data categories in your termbase as you need them and this could include a subject or theme field (probably at entry level). The process is (somewhat) described here - Trados Terminology Documentation. Thanks, Daniel

Hi again, I'm not familiar with Multiterm. I don't find the fields at entry level. I'm supposed to use the structure, but I don't understand how. Do you have a video maybe?
Schönen Abend.
