Can netbootxyz use ISOs hosted on LAN?

[oxwivi]

Instead of downloading over the Internet every time, is there a way I can point netbootxyz to my cache on LAN (whether it's TFTP, SMB, NFS or something else) and use that instead? Or does that necessarily entail self-hosting the complete netbootxyz server?

I was hoping for using the generic PXE boot file and point it to the ISOs on file server while booting into it. I didn't find anything similar in the docs, so if such functionality is not present, I hope this can be taken as a suggestion/feature request.
