You can always put in a new feature request for this filter.
There is always a work around. That is what Admin has told me.
Turn trading off so you will not get any offers. Then move all the Var (you do not want to see) to your want list and you do not need to look at them.
There is a lot of ways members collect and use this site. It appears Admin is trying to help by adding new features all the time. It my look simple but only Admin knows. We have several new feature requests about adding filter here and there that has not been done yet. My understanding is Admin is very busy working on the site to improve it.
