Folder with Multiple Models with Multiple Land Impact - What Number to Put In the Land Impact Field in Marketplace

[Paulsian]

Recently had to redo 30 models 15 of them are similar and range in land impact 1-4 and same with the other 15. 

Vs making 30 folders I was going to group them in 2 folders but the land impact field in market place does not like number ranges says 

There were problems with the following fields:

Master land impact is not a number

Was wondering what to put in that field? Would really love to list  2 folders vs 30

You can leave that field blank if you want, it isn't compulsory. Then it will force people to read the listing if they want to see the land impact of the objects.
