Manipulating the Shape of a Lathe Cutting Tool in Axis

I am running a CNC Lathe using Debian 10 and the latest Version of Buildbot and was wondering if there was a way to represent in AXIS a Lathe Tool that was square having a specific width and the control point positioned to the left (or right) side of the tool (e.g. a cutoff tool)?   ...Just curious.  It would look something like the graphic illustration below where the control point is positioned to the left and the width of the tool is defined as 0.125". 

The only way I know to currently represent a tool like this is to use a diameter of 0.125" in the tool table and that works okay but the graphic puts the control point (+) in the center of the tool.  Usually for a cutoff tool, I do a Tool Touch Off on either the right or left side of the cutoff tool to Automatically update it's Z-offset in the Tool Table.  I would prefer not to have to manually add 1/2 the width of the cutter to measurement provided by the Automatic Offset Calibration to account for the control point being positioned on the center line of the tool in Axis.

Thank you in advance for your help with this,

This would require coding in the core graphics library.
Probably not super hard, but not user configurable for sure.

No worries.  It's easy enough to work around this.  ..just wanted to make sure that I wasn't overlooking something.  Thank you for responding. 

Have a great day,  Barry 

Wait I forgot to confirm that you know you can manipulate the shape to the tool with the tooltable. I am not sure you can set the control point.
I am looking for the docs to show you.

I meant that if you wanted custom shapes, that would require code changes.
maybe you can get something like what you want (I should have read your post better)

best I can find at the moment:
linuxcnc.org/docs/devel/html/gcode/tool-....html#sec:tool-table

orientation (Q) would probably set the control point.
I and J set the front angle and back angle of the display tool shape on a lathe.
