I can I change MultiCam mill end speeds in VCarve Pro?

In VCarve Pro, if I try to edit an end mill and change its feed rate, it reverts back to its original value after I close the Toolpaths window and reopen it.

How can I make that value stick so I can experiment with different speeds?

You can change it in the tool path or in a custom library, but not in the default DMS library.

Ah, thanks. I will try that.
