The filler configuration file Fillers.csv in Formwork placing tools - Walls has been improved. You can now configure usage of filler (custom) parts, whose width can be can be varying and/or parametric. Use the new config fields:

Part1LengthMin – the minimum length/width (the free gap to fill) the product can fit
Part1LengthMax – the maximum length/width the product can fill
Part1LengthProperty – the name of the length property of the custom part. This is needed only if/when the length/width is controlled by a parameter instead of input points
Part1HeightProperty – the name of the custom part parameter controlling the height of the custom part

The fields can be set for Part2, Part3, and so on. Also multiple parts with separate additional rows can be configured. Then you need to keep the Supplier, Family, and Name the same as on the first line.
