Dual Outgoing Connections Failover

Wondering if this can be done any help appreciated, willing to pay for a working config


Equipment
Mikrotik RB2011
Cradlepoint Router set in Bridge mode
Mimosa microwave


What im trying to do is connect a remote site back to a main site with 2 paths

Path 1 VZW cradlepoint to Static IP at Main Site
Path 2 Microwave to Microwave

Would prefer Path 1 to be primary and if it dies go to Path 2

IP setup


Remote Site End Point 192.168.1.100 - Microwave is 1.101 and 102 Master and Slave End point at main site that remote site connects to is 192.168.1.10
Remote site 2 End Point 192.168.1.200 Microwave 1.201 and 202 End point it talks to at main is the same 1.10

Is there away to do this ??
