Beyond League Vs Hc Which Hideout do I keep?

I've done extensive decoration work on my Hardcore hideout, even if the masters might be a lower level than those on the Beyond league, it is the hideout I prefer for my toons. My question is, which hideout do we keep when the Beyond league ends? Can we please choose? Will my Beyond League hideout override my HC one automatically? I need to know because I don't want to lose all of my hard work setting up my HC hideout the way I want it. I'd rather lose my Beyond League hideout when the league ends.
