Universal remote control UI

I have looked around but have not found a solution for the problem. One of the TVs is hooked up to an ancient Sony 5.1 receiver (circa 2010) that can only be controlled through the IR remote. I have a Broadlink wifi remote and have learned all the commands I need. At this point, I would like to have a card that looks like all other receivers, media players or TVs (with a dropdown of the inputs and buttons for play/stop/forward/back/skip forward/skip back. The key feature I am looking for is the quick input change and tuning across the radio presets (yes, I am that old). Does a custom card exist already set up to control a device through a set of service calls (in this case the IR commands) or do I need to synthesize one putting controls together?
