Want the ability to IGNORE specified interferences when running Interference Checks so that in subsequent Interference Check runs these specified "ignored" clashes are not accounted for or displayed. This would allow the user to not have to worry about checking or un-checking certain categories prior to running the check, enabling them to run one (or multiple if there are multiple links) Interference Check and simply ignore certain clashes. One example of an ignored clash would be how Duct Fittings "interfere" with connected Duct work.
