Polar Intersection

As a long time AutoCAD user, I recently began using Draftsight.  After spending some time playing with settings and creating layouts, one major issue that looms.  How, if possible, can I enable Polar Intersections?  Although these may not all be directly related, let me lay out my current settings:

Polar Guides: Enable Polar guides and Display Polar guides checked.  Incremental angles for Polar guide display set to 15.  Display Polar guide at specific angle(s) contains 15, 30, 45, 60, 75 and 90.

EntitySnaps:  Enable EntitySnaps (Esnaps) checked.  Intersection and Visual Intersection are checked.

ETrack:  All items checked.

Let's say I want to draw a line and select an intersection of another object for it to terminate.  I'd like the intersection to show as a snap.  In AutoCAD, this was always accomplished through Polar Intersections and allowed quick sketches.

Thanks,

Dan
