AutoHotKey script that automatically assigns designators to all components with a ? in the designator, like R?, C?.
Since scripting in Altium is a pain, this is an autohotkey script. Sleep times can be adjusted to match your PC's speed requirements. While in a schematics sheet, press Ctrl + Alt + D to run this script. It will go to the tools section, press annotate schematics, create an ECO, accept it and close everything in about one second. I found myself using this pattern a lot of times repetitively, so I felt like it could be automated.
