[sunnyawake5]

Yes, you can specify a custom value and cursor information in the returned value of onPush, which will be present in the arguments of onPop.

export type UndoConfig = {
    mergeInterval?: number,
    maxUndoSteps?: number,
    excludeOriginPrefixes?: string[],
    onPush?: (isUndo: boolean, counterRange: { start: number, end: number }, event?: LoroEventBatch) => { value: Value, cursors: Cursor[] },
    onPop?: (isUndo: boolean, value: { value: Value, cursors: Cursor[] }, counterRange: { start: number, end: number }) => void
};
