Gear on hero + Candidate pick?

[TCArknight]

Quick question -

1) I have an ammo gizmo with an AmmoHelper attached.
2) I have a form_ammo with an amAmmunition chooser table.
3) amAmmunition uses AmmoHelper for the candidatepick, headerpick and addpick and an AmmoExpr field as the candidatefield.

As it is, when I open the chooser table, the selections default to things not added to the hero.

What I would like to do is instead, have it select from any component.Ammunition items the hero is carrying.

Is this possible?
