Selecting artifact dependencies in "Run Custom Build" dialogue

Hi guys,
I've got a build that has a few artifact dependencies. I noticed that in the "Run Custom Build" dialogue, the dropdowns for dependencies to use only has a limited set of them (the last 20 or so). Is it possible somehow to get more than that? Occasionally I need to run a build that is supposed to use a fairly old artifact, and this is preventing me from doing it.

Thanks!

Roman
