Best way to P2V for Proxmox?

Hi.

I would like to P2V up to 50 Windows machines to Proxmox.

Converting with Disk2VHD to VHDX and importing to Raw files is a bit of a pain. Because the hassle of typing the qm importdisk command and attaching it to the receiving VMs will be 50 times.

Is there any way to convert physical machines directly to a raw or qcow2 file? I assume I would need software to run on a USB stick for booting.
