No to this idea because the content is designed as a challenge.The challenge would be lost if you could just skip part of it that makes it the challenge and that's the journey of overcoming the mob mechanics, boss mechanics, item useage etc etc. If you could just go from 100-150 and then reset from 150 it would be a joke because you would bypass 50% of the ambush traps, explosive traps, frog traps, etc etc. The fun of it is knowing you are going to lose everything from one false move and there is excitement to be had when you finally succeed. Making it easier just because you don't want to do the journey again is a poor excuse cause the truth is nothing is forcing you to do all 100 floors in one day. POTD is not designed to be done in one day but ti's the players desire to do it in one day that makes them scream to make it easier because they want to one day it like every other piece of content.

However POTD is something you could do 50/50/50/50 if you start from 1 and go to 200. Then you are looking at about 5hrs each run more or less depending on pace, at least from 100-200 you might be looking at 5hrs to get to 50 floors. but see, even that could be turned into 1hr a day. You get it done in 20 days, is that so bad? No. Enjoy the journey and understand that yes there are huge penalties once you lose, that's what makes it exciting, there is a lot to lose from failing.
