I would like that as well. I play solo Online - Mild ( due to some issues before the patches, as i thought all the problems i had was because i played on Medium, though builded so much on Mild then, that i cant find the motivation to start over in Medium again ).
Everywhere i go, i see grass planks because i have to destroy grass every day, wherever i'm going. I also prefer unused grassplanks decaying faster, since the grass is growing back faster then it dissapears. To compensate that, i just build skybridges across the whole map to make use of the unused grassplanks.
Having so much unused grassplanks also causes the problem that when u sometimes jump or run over it, u get launched in the air like the Hulk is throwing u to the moon.
