Primary and secondary VPN ASA

Hello everyone, I need to set up 2 VPNs from a ASA to 2 remote locations, primary (normally in use) and secondary (standby, used if needed). The issue is that I also need to NAT the traffic from my internal network going out of the VPN to a specific IP for primary VPN and to another IP for the secondary VPN. Any suggestions any how to implement this scenario???

 ____ NAT IP 1 ---- Primary VPN / 

LAN ____ NAT IP 2 -----Secondary VPN

Thank you all in advance
