abstract = {{The multiplexing capabilities of superconducting-based X-ray free-electron lasers (FELs) have garnered significant attention in recent years. The need for wide-ranging photon properties from multiple undulator lines calls for more flexible beam manipulation techniques. To fully realize the potential of superconducting-based FEL facilities, the concept of "beam on demand" has been introduced, offering tailored beam properties for each undulator line at the desired repetition rate. In this work, we present the efforts made at LCLS-II to enhance its multiplexing capabilities, including (1) development of a normal conducting cavity, known as a chirper, to achieve shot-by-shot control of beam compression; and (2) proposal of a multiplexed configuration for the LCLS-II injector to deliver low-emittance electron beams of varying beam charges at high repetition rates. The implementation of these techniques can significantly enhance the flexibility and improve the performance of the facility.}},
