Managing Double Sided Cards?

For me, filtering seems to be a little lacking because of the way I sort my cards.

If a double sided card has a land on one of the sides, that's a land to me, period, end of story.

I can't seem to figure out how to get Deckbox filters (on my inventory) to show me all those cards.  It seems to ONLY show me the ones that are lands on both sides if I select "Is one of" and I can't seem to figure out any way to get a list of all lands (and include any card that has a land on either side) in that list.

Is this a suggestion, or am I just missing a way to do this (or a way to store them differently that's at least consistent?)
