Yes, you can save two or more different configuration files in on single EPCS device. You need at least a Remote Update Controller (ALTREMOTE_UPDATE). Using the controller you can select an application image stored in the EPCS and initiate the configuration of FPGA. Please refer to "Configuration and Remote System Upgrades in Cyclone IV Devices" in Cyclone IV device handbook.

You have to take care of setting the MSEL Pins correct and you must change the configuration mode in Quartus to "Remote".
