Is it not possible to automatically name recorded files using random letters or random Latin alphabet?

[apnms]

While using OBS STUDIO, I want to name the recorded files with random letters or random Latin alphabets, as in the example below, but I can't find a command for this. On the other hand, in the case of dates, there are commands such as %CCYY or %MM %DD.

OBS_anqosoba.mp4
OBS_214aqaob.mp4
OBS_aNGNQAat.mp4

So, does the function to name recorded files using random letters or random Latin alphabet do not currently exist in OBS STUDIO?
