Is there a good way to get access to miniature screws (threaded holes, clearance holes and countersink and bores) in the Hole Wizard?  I have Toolbox, and can find the miniature (#0000 etc. and UNM sizes) in the thread listings, but the sizes are not available in the Hole Wizard.

I have been able to edit the exported Excel file from the Toolbox to add miniature threaded and bottoming threaded holes to the Hole Wizard, by cutting and pasting the relevant sizes from the thread definitions to the thread sizes sheet and then reimporting, but there's no equivalent data in the Toolbox for e.g. pan head miniature screws to allow counterbore or countersink holes to be defined.

Is there a good source of the relevant screw dimensions in Excel format for importing to Toolbox?
