Let's say you're in the army or something and need to bench quickly and be on your way. Is there a "havineinu" equivalent for benching (beyond just stopping after the fourth bracha) that you could use b'shaas had'chak? I've heard the rambams nusach of it was very short, only one paragraph which mentions the themes of each of the 4 brachos. Could this be used - or even just saying in English "thank you God for sustaining us, eretz yisrael, yerushalayim and being a" tov u'meitiv"? Is so, should the full version of benching be said later on, assuming you're still within the time frame to bench?
