Is there any way to get keys or items greyed out when you make multiple bids?

[Krash!!]

I am an avid trader and love the ability to bid on these amazing items, however, I sometimes do some larger bids and just experienced this first hand. I bid 18 keys in one bid and then 4 in another , well everything was smooth as silk until i was outbid, that wasnt the issue though, i went to re-counter and everytime i tried to put my bid back in it was saying "some of the items are in another bid" , well i'd gone and bought another 12 keys, and i had to filter through ALL keys in my back pack one at a time to get just 4 that werent in the 18 bid .. and it was an ABSOLUTE nightmare.  I thought i'd both ask here if there is a filter or something that will grey out things used in a different bid or if you have to go through everything one by one everytime? and if thats the case, could something be implemented to do such a thing as to make this "re bidding" easier. Thanks for reading and keep up the great site!!
