I brought this up on the older forum. this is when you have your plant manager up, under the "size" column. it would be super convenient to click on the plant material, bring up a pull down and change size. as well ad possibly add options to add new columns for spacing, canopy, and so on. we find this particularly a nuisance when we have value engineer projects, especially when you have about 25-30 kinds of groundcover or shrubs work with. first we like to change the plant container size, if that doesn't fit the budget, we would change the spacing.
