Generic "Wait X Days" option added to town inns

I feel the game needs a generic "wait for x days" option added to the town Inn (or allow the "Rest" option to be used even if no one is fatigued). I found myself in a situation where I had 8/8 mercs in my company, 4 were in the infirmary, and 4 were ready to go and completely rested. I could not leave town because i did not have 5 members ready to go to form a party, and I could not pass time because all 4 that were not in the infirmary were fully rested.

I thought that playthrough was completely borked but thankfully when i loaded the game back up the next day, it started me outside of town so I was able to move on the map and waste time until one of my guys was healed up in the infirmary, but barring that accidental discovery, I had no way to continue playing and was trapped in town unable to do anything.
