Filter items on groups with Avg Daily Sold value
Selft explanatory; it would allow to create subgroups with items that are sold for say, more than 1 per day on avg.
Imagine you have a list of 1000 crafted item, at the moment you can't easily know which one it's worth to craft for quick profit.
With this, you create a subgroup, filter out the 20 items that sells well and worth more than 1k, then you craft.
There's a lot of other useful uses.
If we could use our own saleRate in custom prices we could do this ourselves just use boolean tests etc using combined check () functions... Still easier your way just this might be easier to implement
