How is the Overstrength Factor, Lambda 0, handled by PROFIS

How is the Overstrength Factor, Lambda 0, handled by PROFIS

Background: Code of Record is ACI 318-14
Questions: I understand that the PROFIS software defaults to Section 17.2.3.4.3.a of ACI 318-14 for using a ductile anchor. Questions are: (1) If the user wants to use a non-ductile anchor, how is that option (17.2.3.4.3.d of ACI 318-14) entered into PROFIS? (2) How is the Overstrength Factor (multiplier) for seismic loads, that is required by 17.2.3.4.3.d for a non-ductile anchor, handled by PROFIS? Must the user input the value of the Overstrength Factor and PROFIS increases the loads accordingly or do the input loads to PROFIS by the user already need to have the factor included? Or is the Overstrength Factor handled in some other way by PROFIS? Please be specific. (3) How do the results from PROFIS show that the Overstrength Factor was used and how is an acceptable or unacceptable design denoted within the results that are printed out by PROFIS?
