There is a box you can tick to filter on holiday sales, is this what you are asking about?
With regards to position of the models, I think that gets sorted on amount of sales they generate.
Personally I think this is not really important at all because my new models usually also end up last and then after while getting sold couple of times end up front, but not get more average sales because of that.
I would argue good tags and other efforts in getting good Google ranking and so forts is more important.
You can basically be a strange duck and still get relative good sales even in background on CGt as long as people can find your things easily if there looking for it online.
I took a look at your things and they are actually ranking very well here on CGt?
If I type bucket (even left out medieval) then it shows up front page.
Same for well etc.
Probably best not overate the position, it is not biggest factor in getting more sales.
