I need to split my umx61 so different parts of the keyboard transmit through different channels. Is that possible?

A wireless system consists of a receiver plugged to the USB port of the computer, a mouse and a keyboard. The function of the receiver is to "listen" to the signals sent by keyboard and mouse. As there might be other wireless equipment operating within range of the receiver, ALL systems, independent of brand, have many different channels in which they can operate, without interfering with other devices. The mouse and the keyboard, separately, have to know which channel the receiver is working on, in order to transmit on that particular channel.
Most system failures (other than depleted batteries) can be attributed to the receiver " listening" to a different channel than the mouse/keyboards are transmitting on.
Resetting the system, to work on the same channel, may vary from manufacturer to manufacturer, but basically all work with a button on the receiver that changes / resets the operating channel, and within a short period of time, similar buttons on the back of mice and keyboards that must be activated in order to "learn" the new channel set by the receiver.
