WAN Bandwidth aggregation with multi VPN connections

Hi,

I am trying to figure out if Sophos XG can support WAN Aggregation (not MultilinkPPP) via VPN and then redirect internet traffic from within. Some of this technologies refers as below :

https://www.simonmott.co.uk/2012/03/vpn-bonding/

This is not new, although I am quite surprise why Sophos didn't include this rock feature in it's box ? Maybe this can be combined with Cloud services too like Amazon, Azure, etc etc, or even Sophos XG VMWare.

If anyone have ideas, please let me know

Thank you
Panos
