Prevent wall cleanup

[bimologist]

I have a Exterior Foundation/Retainwall drawn in as a Structural Wall. I am adding a Interior CMU wall which ends up growing and will not end at the edge of the Concrete wall
How does one go about preventing this cleanup.
thanks

Highlight the wall, then right click the blue dot at the end of the wall and chose disallow join.

Thanks for the quick reply. Works better than edit Wall Join, which I was able to achieve , but the wall Blue dot was longer still

thanks
