The Nucleus class atg.nucleus.ResolvingMap lets you link the value of a map key to another component property, through the ^= operator:

myResolvingMapProperty=\
   key1^=/component-name.property-name
   key2^=/component-name.property-name
 ...

Note: No white space should precede or follow the ^= operator.

For example, the following property setting links the value of activeSolutionZones to another component property textActiveZones property:

relQuestSettings=\
  activeSolutionZones^=/MyStuff/MyIndexingOutputConfig.textActiveZones
