in Coldfusion how do I add a 'column' to the struct inside an array?

Question

For example I have array ads and inside it has images

ads
   images
      url = someurl
      title = sometitle
      *here I want to add prop = someprop 
   images
      url = someurl
      title = sometitle
      *here I want to add prop = someprop
ads
   images
      url = someurl
      title = sometitle
      *here I want to add prop = someprop

Now I loop

<cfloop array="ads" index="i">
   <cfloop array="i.images" index="j">
      <cfif somecondition>
         <cfset prop = 'yes'>
      <cfelse>
         <cfset prop = 'no'>
      </cfif>
      <cfset ArrayAppend(i.images[j],prop)> ???
   </cfloop>
</cfloop>

I tried several things with the ArrayAppend, tried a StructAppend, but apparently I am unable to understand how I would go about.

You were close. You can simply set the prop on the item in the images loop. This is assuming that the items in the i.images array are structures.

<cfloop array="ads" index="i">
   <cfloop array="i.images" index="j">
      <cfif somecondition>
         <cfset j.prop = 'yes'>
      <cfelse>
         <cfset j.prop = 'no'>
      </cfif>
   </cfloop>
</cfloop>
