Well I am afraid that can be done... anyways if the size is really bothering you, then you can make the display number invisible by checking the box and then place "text" on each pin with its "number", as you can easily play with text size and color etc...
you asked for font option in version 10, in which there is no such option, the attached doc is for Version 13 which has this option and you can set the font that you like!
