2 WAN bonding on AWS CHR 7.8

Hi all, I have a problem that I can’t figure out.

I have two mikrotiks, one physical and one on AWS.

Network1: Local carrier
2 WAN with 2 static public IPs, 100mbit/s link
Downstream of the two WANs is the Mikrotik, with two links WAN1 and WAN2, with load balancing and failover

Network2: AWS CHR Mikrotik
1 WAN with public address

Now my problem is the following, I have to establish two links from NETWORK1 to NETWORK2, and on NETWORK2 aggregate the two incoming flows on a single interface which then exits with a single ip, and with the aggregated bandwidth.

I managed to set up this setup with OpenVPN on a Linux Ubuntu server, but I can’t do it on Routeos.

Can I use VPN or other type of link…

Please help me cause I’m freaking out…
