Add custom hole size to hole wizard / toolbox

Hello SW User

I am looking for a way to add just custom hole that let the user enter the number they want.

I have copy (2) folder ANSI Inch & ANSI Metric to new standard folder but there is almost no way for me to add custom hole so we can use as entry hole in the model. Right now if we use the 1/2" hole and use the custom to enter .505 the model tree still call out 1/2" (.505) I just wonder if I can add custom hole size and the user enter the hole size they want and model browser show the correct to that hole dia.

See the picture for more detail.

Thanks
