Conquest Exodus available for Solo/Co-op

I saw that conquest exodus mode is available for online multiplayer but not for solo/co-op. I 100% play on solo/co-op mode and would love to play the older maps too. I know i could just play portal mode and add bots, but the progressing in portal mode with bots sucks. I know that at one point in the past, they had a conquest exodus mode for solo/co-op. Could you guys add that back in the game to add more maps for solo/co-op players? It shouldn't be that hard to implement in the game, since it is available in online multiplayer mode.
