Drilling toolpath with threadmilling selected uses wrong feedrate when plunging

When using the drilling toolpath with threadmilling selected, Fusion chooses to use the cutting feedrate instead of the plunge feedrate when plunging. This makes threadmilling unnecessarily slow when using desktop or lighter duty mchines where you need to take many light passes.

Is this something that can be fixed? I find the drilling threadmill cycle much simpler and easier to set up than the 2D threading toolpath when threadmilling. But the 2D thread rapids to the bottom of the hole correctly and runs quicker.

The Threadmilling (inside the Drilling cycle) is really intended for machines that have control-specific thread cycles, such as Siemens or Heidenhein (I'm sure others exist as well). What exactly about the actual Threadmilling cycle do you find troublesome or difficult to implement?

its just easier to use the final diameter input vs pdo. But I get it
