As far as I know, you'll have to add a standard by entering a .txt file with the different dimensions in it.
As an example (helicoil screw-thread)
ThreadDiam. Pitch HoleDiam. M
3.08mm 0.45mm 2.60mm m2.5
3.65mm 0.50mm 3.10mm m3
4.91mm 0.70mm 4.10mm m4
6.04mm 0.80mm 5.20mm m5
7.30mm 1.00mm 6.20mm m6
Standard can be added under the hole-function
