RAM FRAME Change unbraced length of brace member

In RAM FRAME, I have a SCBF (cross brace). Cross Brace members are connected to each other at mid-point when they intersect so I want to set the unbraced length in strong axis to half of the total length.  I cannot find a way to do that so I modified K=0.5 strong axis instead.  Also  I want to override the length of the brace member.  Currently, RAM seems to calculated it from work point to work point.  However, the actual length of brace member is between hinge zone of gusset which can be up to 4 ft different than work point to work point length.  How can i alter that? Should i just calculated the % different between actual length and RAM calculated length then change the K factor instead again?
