Combine epochs from separate .epo files containing different events

Dear MNE users,

I am analyzing EEG data from an experiment in which participants completed different conditions in separate recording sessions - let's call these 'conditionA' and 'conditionB'. Data from each recording session contains events denoting 'correct' and 'incorrect' responses to stimuli. Data from each recording session was pre-processed separately, such that I now have two .epo files per participant (s1_conditionA.epo, s1_conditionB.epo, s2_conditionA.epo and so on).

I would like to combine epochs for each participant into a single object, such that 'epochs' will contain four types of event: 'conditionA_correct', 'conditionA_incorrect', 'conditionB_correct', 'conditionB_incorrect'. Any advice would be greatly appreciated.

Thanks!
