Custom Expression conundrum

[Redcap's Corner]

I've been using custom expressions to build lists of creatures of particular types and sizes using the following basic formula:

(HasType.tpMonHuman & (RaceSize.Small11 | RaceSize.Medium0))

Unfortunately, now I need that list of all creatures of a particular subtype and size. Unfortunately, it would seem subtypes are directly bootstrapped onto races, rather than being expressed through tags. So, is this possible?

I need to construct a custom expression that builds a list of Large-sized giants.

You might try nested foreaches. Not generally recommended because it can be expensive for the processer, but could work...

Something like:

var finalexpr as string
var tempstr as string

foreach thing in BaseRace where "HasType.tpMonHuman & (RaceSize.Small11 | RaceSize.Medium0)"
  tempstr = "Race." & eachthing.idstring

  ~ If our current iterated race has the correct subtype bootstrapped, then add the temporary string for this race to the final candidate expression
  foreach bootstrap in eachthing where "component.Subtype & thingid.stGiant"
    finalexpr = splice(finalexpr,tempstr, " | ")
    nexteach
  nexteach

field[usrCandid1].text = finalexpr
