Hello,
yesterday i have created a post on the German forum regarding Lists for Components and Materials and their limitation in Sorting&Grouping Tables.
As of right now, you can only add 4 Filters/Parameters to the Sorting&Grouping which can be limiting in some cases
(mine for example being the following regarding Airductcomponents: System, Phase created, Family, Size, Area(custom) which are 5 in total)
even when you already limit yourself by grouping or removing some parameters beforehand and sacrificing your initial structure of the sheet.
Now, what would i like to suggest is that the amount of fields just gets upped to at least 10 or, which in my oppinion is just much cleaner, have it generate x+1 fields whenever you add/edit one, such that you only have as many fields as currently necessary.
