PXE boot different computers with different auto startup options?

Hi

Is it possible to configure ASD3 PXE server to set different bootmenu items as default depending on which computer boots from PXE?
I want to PXE boot some computers with OS auto startup and some other computers with Acronis Agent auto startup.
With the "Configure PXE Server" option i can only add or remove Acronis Agent and Master Image Creator, but what i set here as default bootmenu item, it will be the default for ALL computers that boot from network.
This is really inconvenient, because if i set Acronis Agent as default startup, then all computers will start the Acronis Agent, and i only need some select computers to start the Agent, not all of them. And if i set OS startup as default, then i have to manually start the Acronis Agent on each computer, where i want to deploy an image, which defeats the purpose of network booting.
Maybe i'm missing something here, but i can't figure out, how i could configure this in the Acronis PXE server.
If the Acronis PXE server is not able to do this, then are there other solutions to solve this problem? With a Linux PXE server maybe?
