Multiple types considered as one class to selection and BuildLimit

Well, someone posted a request about having a VeteranClass= and EliteClass= setting, so "Select all of this type" will work for units that have undergone transformation after promotion to Elite. And someone has requested to include a function to transform a building into another building after it has fired its superweapon. IMO, the VeteranClass=/EliteClass= setting, if implemented, should be expanded, so a building that has been transformed from another building by firing its Superweapon does count towards the BuildLimit= of the original building. I'm thinking about something like:

[EXAMPLE_OBJECT]
BuildLimit=1
;VeteranClass=;obsolete
;EliteClass=;obsolete
SameClass=EXAMPLE_OBJECT_VETERAN,EXAMPLE_OBJECT_ELITE,EXAMPLE_OBJECT_AFTER_SW ; list of objects that count toward BuildLimit and Selection of parent building.
