Plunge/Groove with neutral-hand insert

[alundRQ4XG]

I'm trying to rough the v-shaped grooves on the pictured part. I'd like to rough these by plunging straight down (x-axis) with a neutral-oriented V (35° diamond) insert. I can (only) get the "Turning Profile Rough" and "Turning Profile Finish" toolpaths to work with this tool, but I can't use "Vertical passes" with the roughing--I get an "Invalid Value" error...

I can get a toolpath that cuts along the Z-axis, but I will get better performance & cycle time by plunging.

Anything I'm doing wrong here, or any way to hack around this?

(Second image is the best roughing toolpath I've been able to get with horizontal passes, and the error message I get trying to set it to Vertical passes)

Sadly, I don't think this is going to be possible. I'm chatting with the Project Manager for Turning to see if there's some workaround we can suggest, but I'm not too hopeful about it at the moment..

Thanks @seth.madore for taking a look. I can get the actual code by setting up my tool as a grooving tool, but obviously that doesn't simulate correctly.

I tried to hack around this by making a Single Groove operation, Protecting the operation, and then editing the tool back to the VNMG shape. For some reason, the simulation always shows the VNMG cutting to a deeper depth after I do this switch.
