Generate random ID to create record

Maybe i miss something but how i can create a variable with random text to create an unique ID before create a record. My use case is create record from machine tags to create live analysis (kind of SPC chart) that i will included in an app.

@youri.regnaud you’re not missing anything, we are still adding some of these features. Specifically, the ability to access ‘current date and time’ and expressions for generating random strings. Additionally, we are introducing access to all machine attributes for a machine, which would allow you to utilize any attribute that might also provide a random id. However, I just responded to your other question regarding machine events (you don’t have these on right now).
