Is it possible to build a filter to compare bid/buyout price vs. vendor price?

Additionally, is it possible add vendor price for all items automatically rather than collection? Informant contains these values and does this currently. I'm not sure if it would be easier to import the information into Aux or to just let Aux call to Informant.

Please let me know if one of both of these can be done currently.

The filter is vendor-profit/bid-vendor-profit
