Make completing scenarios a little bit more fun

The typical pipeline of every scenario (at least for me) is as follows: establish self-sustanable beaver colony, play a little bit with terraformation to make your colony resistant to disasters (which I personally like the most), optionally expand your colony or make new ones, build final monument.
After several plays the 'bulding final monument' part becomes tedious and extremely boring. Sometimes I just run the game and go for a walk with dog so the building can be finished. I'm not sure this is what final stage of the game should look like.
I'd recommend revamping the last stage, for instance customize each scenario with 5 missions/tasks, one of them would be building the final monument (after cost decrease), two might be related to colony development (for instance sufficient number of wares, number of beavers), two related to terraforming (for instance for map with 5 water basins a task could be to dry the basin). Ideally, each scenario would have its custom tasks to complete.
