Templates for gcode file filenames

Suggestion Summary

Provide the facility to have standard patterns for output filenames, with placeholders that can be replaced with things like printer profile name, filament type, layer height, date/time, object name(s) etc

Slic3r and PrusaSlicer support this kind of filename templating (although a definitive list of variables you can use isn’t anywhere obvious)

Why is this useful?

When automatically uploading gcode to octoprint or duet, the suggested filename will be something sensible and often correct enough to send on without changes.
