Feature Request - Millisecond token in filenames

I’ve previously posted a request for the ability to include a filename option that includes millisecond resolution. See my original posting saved under an inappropriate category, Filename format extention

This is to enable better support of programmes that require the accurate recording of exposure times in the filename. At the moment the ‘DateObs’ variable within FITS headers varies with regard to showing decimal seconds in the recorded time of exposure but it’s not clear whether or not it actually populated consistently. In addition the filename format tokens do not allow such accuracy.

Having the ability to include an accurate time in the filename will greatly enhance my local Astro Societies Pro/Am study contributions.

Thanks
