Is This Possible?

Hi 

    I use corel wih my laser cutter

If I set the outline pen to hairline ( the narrowest  ) my laser cuts outlines twice, once each side of the line 

so before I start I have to remember to type in a value of 0.01mm for the outline pen width  and then my laser accepts this

as a single line and cuts just once 

Is it possible to add this 0.01mm to the list of clickable choices so it appears in the drop down list  rather than have to type i in every time ?

and even better can I make it default to this size on startup ?

Regards

Don
