Just change the recommended width setting for the net/pin pairs of interest.
Select them in the the layout editor then RMB "Show Rules", Clearance".
Rules are rules for a reason.
There are some cases that you set the min and the max width, but then you want to choose any width between them. Also, there are other cases in wich setting rules for every single net it's just a waste of time or not needed.
In most of the CADs is possibile to temporarily set a width between min/and max with a mouseclick and keep it for a while. In Mentor PADS, as usual, it seems is not possible... unless repeating everytime the command with the "w" shortkey, wich is quite annoying.
Having a completed rule-driven layout is a good thing, but sometimes you may need some "flexibility".
